Overview

Compiling BGL

The BGL Compiler is primarily used to compile scenery and airport data into files that ESP can read. It is also used for creating Rewards files for the mission system, and adjusting time zone information.

GUID Formats

GUIDs are now entered in the following format (complete with curly brackets and dashes): {93802d8b-ba4f-45eb-a272-9f029a0feeb3}. The example shows a GUID for a water tower. In earlier versions of ESP, GUIDs were entered as a 32 character hex string.

See the SDK Overview section on Generating GUIDs to access a tool that will generate new style GUIDs. If for any reason GUIDs need to be converted from the old format to the new, or vice versa, use the following piece of C# code. If an old format GUID is provided as the parameter, a new format GUID will be returned, and if a new format GUID is provided as the parameter, an old format GUID will be returned.

        public static Guid ChangeGuidFormat (Guid guid)         {             string guidString = guid.ToString ("N");               guidString = string.Format ("{0}{1}{2}{3}{4}{5}{6}{7}{8}{9}{10}",                 guidString.Substring (0, 8),                 guidString.Substring (12, 4),                 guidString.Substring (8, 4),                 guidString.Substring (22, 2),                 guidString.Substring (20, 2),                 guidString.Substring (18, 2),                 guidString.Substring (16, 2),                 guidString.Substring (30, 2),                 guidString.Substring (28, 2),                 guidString.Substring (26, 2),                 guidString.Substring (24, 2));               return new Guid (guidString);         }

Compiler Usage

If you are running an operating system earlier than Windows XP you will need to ensure that MSXML4 is installed on any machines that will run BGLComp.  You can find MSXML4 on the Microsoft web site: https://www.microsoft.com.

If you are running the Windows Vista operating system you will need to be working as an administrator for BGLComp to work correctly.

The BGL compiler is invoked with the command:

bglcomp.exe <filename>

To make batch file processing easier, the compiler will accept wildcards to process multiple files per invocation.  Invoking the compiler without any parameters will print version and usage information for the compiler.  Along with the compiler is the file BGLComp.xsd, this file must be located in the same directory as BGLComp.exe for the compiler to function properly.

About the XML Format

The scenery format is XML-based and follows a strict file structure with regards to element hierarchies, case sensitivity, and the contents of elements (potentially including white space).  XML is a text-based file format consisting of elements and attributes.  The XML specification also allows for comments, to allow scenery files to be annotated.  At this time elements, attributes, and values are all case-sensitive.  The XML convention used is as follows:

  1. All significant words in elements capitalized.
  2. The first letter of an attribute is not capitalized, but the successive significant words are.
  3. All letters of an attribute "value" are capitalized (unless otherwise specified) and words are separated by underscores.
  4. It is OK to include blank lines in the XML files to improve readability.
  5. The order that attributes appear for any one object is arbitrary.
  6. The keywords "YES" and "NO" have the same meaning as "TRUE" and "FALSE".

See the Microsoft website (www.microsoft.com) for more information about XML.

Scenery File Format

The following is a sample of the XML file structure used for scenery files.  Note the use of "<!--" and "-->" to start and end comments.

<?xml version="1.0" encoding="ISO-8859-1"?> <FSData      version="9.0"      xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'      xsi:noNamespaceSchemaLocation="bglcomp.xsd" > <!-- Facility and scenery data goes here --> </FSData>

  • The first line of the file indicates the XML version and character encoding to use for the rest of the file.  This line is not strictly required by XML parsers, but is strongly recommended to ensure the XML parser produces expected results.
  • The second indicates the start of the data.  The tag FSData is considered an element and indicates what kind of data is present in the file. 
  • Following the FSData tag is an attribute: version.  Attributes are immediately followed by a value enclosed in quotes.  For scenery, the FSData element must be followed by a version attribute and that version must be "9.0".
  • The remaining attributes on the line are directives to the XML parser that tell it how to validate the contents of the XML file.  These attributes must be present in all scenery XML files and match the above sample.  Once all of the attributes for the FSData elements have been specified, the element is closed with "/>". 
  • Following the declaration of the FSData element will be the XML that defines the contents of the file.  In this example the file content is simply a comment. 
  • To finish off the file, the </FSData> element is specified. 

For more information on how to create new terrain refer to the Terrain and Scenery document.  Both facility and scenery information may be contained in a single .XML source file and this practice is encouraged.

Spatial Sorting

Spatial sorting is important to reduce file size and increase engine efficiency.  It is up to the scenery creator to break the source into geographically related areas to optimize how the scenery is loaded into memory.  When deciding on boundaries it is beneficial to avoid overlapping file bounds between files.

Common Errors

The XML compiler has been designed to be very strict in an effort to avoid ambiguity.  As a result, the strings used for XML elements and attributes are treated as case-sensitive.  The compiler will report such errors at compile time.

Some scenery elements are not allowed to contain other sub-elements.  The form of the XML is used to distinguish between these types of elements. 

Elements allowed to have sub-elements take this form:

<Element attribute="value">       <SubElement>             <!-- Sub element data -->       </SubElement> </Element>

Elements not allowed to have sub-elements take this form:

     <Element attribute="value" />

If an element that is not allowed to have sub elements isn"t closed with "/>" or contains any data (including white space) before the closing element tag, the following error will result:

ERROR: 19, 66, Text is not allowed in this context according to DTD/Schema.

The XML standard is very strict in this regard and it is essential to have the proper closing on an element. If the element is allowed to contain data, the element is closed with a declaration of the element prefixed with a "/" character (i.e., </ClosingElement>).  If the element is not allowed to contain sub-elements the declaration is closed with "/>".  This is an important distinction that will be checked during XML validation.  The appropriate structure of these elements will be shown in their descriptions.

When errors are reported from the compiler, they generally start with the line number and character position on the line where the error occurred.  This format is mainly used when an XML format error occurs and sometimes when a data content error occurs. All of the .XML content is validated against an .XSD to ensure proper file structure before processing in the compiler.  As a result, ordering of sub-elements is verified.  If elements are found to be out of order, the following error will result:

ERROR: 5, 48, Element content is invalid according to the DTD/Schema. Expecting: Effect, GenericBuilding, LibraryObject, Trigger, Windsock, AttachedObject.

This is .XSD validation code reporting what it expects to see next.  Check the XML at the line noted and see if there is an element that might be out of order, or whether multiple instances of a sub-element are allowed. 

Entries in the ESP.cfg File

Some of the entries in the ESP.cfg configuration file reference scenery, terrain and graphics issues. The ESP.cfg file is found in the C:\Documents and Settings\<user name>\Application Data\Microsoft\ESP folder (for Windows XP) or the C:\Users\<user name>\AppData\Roaming\Microsoft\ESP folder (for Windows Vista).

[Scenery] Section

MissingLibraryAlert=1
Receive error messages when library objects are referenced but not found, or when library objects that have bounds are referenced outside of those bounds (for example, the Seattle Space Needle model can only be referrenced in the Seattle locality).
ShowMissingTextureAlert=1 Receive warnings when one or more scenery object or aircraft model textures are missing. Note that setting this will not trigger an error message for missing terrain textures.

[Graphics] Section

Day_Threshold A value between 0 (total darkness) to 65535 (full day sun at noon in summer) that represents the amount of ambient light to apply to textures at the end of the day/night threshold. The default value is 32768 (50 percent of full brightness). The smaller the difference between Day_Threshold and Night_Threshold, the quicker twilight and sunrise will be.
Night_Threshold The default value is 4096 (6.25 percent of full brightness).

XML Format

Scenery objects are placed inside of the <FSData> elements.  The following XML shows the XML file structure used for scenery objects and will put an oil drilling rig next to the runway at SeaTac airport.

<?xml version="1.0"?> <FSData      version="9.0"      xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'      xsi:noNamespaceSchemaLocation="bglcomp.xsd" > <SceneryObject       lat="N47 25.89"       lon="W122 18.42"       alt="0"       altitudeIsAgl="TRUE"       pitch="0"       bank="0"       heading="0"       imageComplexity="NORMAL">       <LibraryObject             name="{93802d8b-ba4f-45eb-a272-9f029a0feeb3}"             scale="1.0"/> </SceneryObject> </FSData>

All scenery objects are contained within a SceneryObject element.  The SceneryObject element has several required attributes that define the placement of the object in the world.  For this sample, the SceneryObject contains a LibraryObject that represents a water tower. 

  1. Copy the above sample into Notepad (or another text editor) and save it to disk.
  2. Run the BGLComp compiler on the file and a resulting .BGL file will be created.
  3. Copy the .BGL file to the Scenery\Generic\Scenery directory, and run ESP.
  4. Select the default startup flight and you will see a placement of the drilling rig in just off the runway at Seattle Tacoma International airport.

The following sections list the elements and associated attributes that can be used to create scenery.  Some scenery XML elements are used to contain other elements, while others are not.  This distinction is shown by the form of the data.

SceneryObject

This element is used to designate an object"s placement in the world.  It can be used to specify the lat, lon, alt position of the object, and the pitch, bank and heading to be applied.    This element is allowed to contain Bias, Beacon, Effect, GenericBuilding, LibraryObject, Trigger, Windsock, AttachedObject data and should not be terminated with "/>". The AttachedObject entry must be the last.
 
<SceneryObject       lat=" 32.69398294"       lon=" -16.77601783"       alt="0"       altitudeIsAgl="TRUE"       pitch="0"       bank="0"       heading="0"       imageComplexity="NORMAL">       <!-- Scenery object data elements -->       <BiasXYZ           biasX="0"           biasY="0"           biasZ="0"/>  <!-- Optional -->       <LibraryObject           name="GUID"           scale="1.0"/>       <AttachedObject ......>       <!-- Optional -->       </AttachedObject> </SceneryObject>

instanceId Optional GUID that identifies this SceneryObject entry. GUID in the format: {nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
lat Latitude of object -90 to +90 degrees
Format can be decimal or degrees-minutes-seconds
lon Longitude of object -180 to +180 degrees
Format can be decimal or degrees-minutes-seconds
alt Altitude of object Any floating point value. May be suffixed by 'M' or 'F' to designate meters or feet. Default is meters.
altitudeIsAgl Boolean indicating whether altitude is AGL or MSL TRUE = alt is AGL
FALSE = alt is MSL
pitch Pitch applied to object 0.0 to 360.0 floating point value
bank Bank applied to object 0.0 to 360.0 floating point value
heading Heading applied to object 0.0 to 360.0 floating point value
imageComplexity Minimum image complexity setting for the objects to appear. For example, objects set at NORMAL will appear if the setting is DENSE, but not appear if the setting is SPARSE. VERY_SPARSE
SPARSE
NORMAL
DENSE
VERY_DENSE

The following elements can be added to a SceneryObject, but contain no additional attributes or elements, so are entered into the XML, for example, as <NoAutogenSuppresion/>.

NoAutogenSuppression Do not suppress Autogen created objects that might be on the same terrain as the scenery object.
NoCrash Aircraft do not crash if they hit this object.
NoFog Fog does not affect the object at render time (useful for the virtual EFIS objects that draw in the sky).
NoShadow Objects do not create a shadow.
NoZWrite Allows an object to draw into the scene but not write to the ZBuffer. Note that there is no control over the draw order.
NoZTest Allows an object to draw into the scene without testing against the ZBuffer. This causes objects to draw on top of others. Note that there is no control over the draw order.

BiasXYZ

This element is used to add an X, Y, Z bias in meters to the placement of an object.  The acceptable range of values is unbounded, but it is recommended that biases only be applied for small distances.  If this element is used inside of a SceneryObject it must come before any instances of AttachedObject, Effect, GenericBuilding, LibraryObject, Trigger, or Windsock.  This bias is not affected by pitch, bank, or headings applied to the base scenery object. This element is not allowed to contain other data and must be terminated with "/>".

<BiasXYZ       biasX="0"       biasY="0"       biasZ="0"/>

biasX Bias along the longitudinal axis in meters Floating point value
biasY Altitude bias in meters Floating point value
biasZ Bias along the latitudinal axis in meters Floating point value

Effect

This element is used to add a scenery effect to the scene.  See Creating Special Effects for more information about creating and using scenery effects.  This element is not allowed to contain other data and must be terminated with "/>".

<Effect       effectName=" FW_Controller"       effectParams=" MOY=01,01;DOM=01,01;HOD=00,00;MOH=00,20;"/>

effectName Name of the effect String (up to 80 characters)
effectParams (optional) Parameters for the effect. See the Special Effectsdocumentation for more information. String of parameter settings, may be empty.

GenericBuilding

This element is used to add a generic building to the scene.  The building type and parameters are set as sub-elements.  This element is allowed to contain RectangularBuilding, PyramidalBuilding, and MultiSidedBuilding data and should not be terminated with "/>".

<GenericBuilding       scale="1.0"       bottomTexture="68"       roofTexture="25"       topTexture="68"       windowTexture="41">       <!-- building data --> </GenericBuilding>

scale Scale value for building that represents the number of meters per unit. Set to 1.0 for the building to be modeled in meters. Floating point value.
bottomTexture ID of texture to use on bottom layer. Integer. See Generic Wall Textures.
roofTexture ID of texture to use on roof Integer. See Generic Roof Textures.
topTexture ID of texture to use on top layer Integer. See Generic Wall Textures.
windowTexture ID of texture to use on window layer Integer. See Generic Window Textures.

The textures for walls for generic buildings are divided into two. The lower half provides textures for one design of building, and the upper half for another. The textures for roofs and windows are not divided into two, the whole texture is used. In the examples in this document the following textures are used:

68/69 This texture is for skyscraper buildings, and is divided into four regions. The lowest shows the bottom layer (street level) of a building. Just above it is the top layer that is rendered above the windows. The third layer is an alternative lower level (street level again), and above that another top level. The texture number 68 references the bottom layer, and number 69 the top layer. This texture is 128x128 pixels,
68/69 This texture is used for the building walls at night time.
25 A roof texture, clearly designed as the flat roof top of a skyscraper, although we use it for many of the building examples here. This texture is used for both day and night time. The texture is 128x128 pixels.
41 This texture is used for skyscraper windows. It is 64x64 pixels.
41 This is the window texture used at night time.

RectangularBuilding

This element is used inside of a GenericBuilding element and is used to describe a rectangular building.  Rectangular buildings have many possible attributes and the availability of attributes is determined by one of four roof types: (FLAT, PEAKED, RIDGE, SLANT).
This element is not allowed to contain other data and must be terminated with "/>".  The following is a list of the valid roof types and their attributes:

Rectangular Building: Flat Roof

<RectangularBuilding          roofType="FLAT"       sizeX="44"       sizeZ="44"       sizeBottomY="5"       textureIndexBottomX="512"       textureIndexBottomZ="512"       sizeWindowY="250"       textureIndexWindowX="1024"       textureIndexWindowY="2048"       textureIndexWindowZ="1024"       sizeTopY="5"       textureIndexTopX="512"       textureIndexTopZ="512"       textureIndexRoofX="256"       textureIndexRoofZ="256"/>

sizeX Size of base along longitudinal (east-west) axis in meters. Non-negative floating point value
sizeZ Size of base along latitudinal (north-south) axis in meters. Non-negative floating point value
sizeBottomY Height of bottom layer in meters. The lowest region of the wall texture is used here. Often the intended value for this is 5 (5 meters), but if you enter 10 for example, the texture will be stretched to fit. Non-negative floating point value
textureIndexBottomX The Texture Ratio for the bottom wall in the X direction of the building. Non-negative integer
textureIndexBottomZ The Texture Ratio for the bottom wall in the Z direction of the building. Non-negative integer
sizeWindowY Size of window layer in meters. For a skyscraper this is often several hundred meters. Non-negative floating point value
textureIndexWindowX The Texture Ratio for the window texture when being rendered along the X direction of the building. Non-negative integer
textureIndexWindowY The Texture Ratio for the window texture when being rendered along the Y direction (up) of the building. Non-negative integer
textureIndexWindowZ The Texture Ratio for the window texture when being rendered in the Z direction of the building. Non-negative integer
sizeTopY Size of top layer in meters. Again for a skyscraper this number is often 5 meters. Non-negative floating point value
textureIndexTopX The Texture Ratio for the top of the wall in the X direction of the building. Non-negative integer
textureIndexTopZ The Texture Ratio for the top of the wall in the Z direction of the building. Non-negative integer
textureIndexRoofX The Texture Ratio for the roof texture in the X direction of the building. Non-negative integer
textureIndexRoofZ The Texture Ratio for the roof texture in the Z direction of the building. Non-negative integer

Texture Ratio

When referencing textures for GenericBuilding, a calculated ratio is used to determine how often the texture is repeated in the given space. The calculation is the given number, divided by 256. This evaluates to the number of times the texture is repeated. It does not matter if the texture is 64x64 pixels, or 512x512 pixels, the same calculation (division by 256) applies. So, for example, if the value for textureIndexBottomX is 1024, then the lower level texture is repeated four (1024/256 = 4)  times across the building. If the number 384 had been entered, then the texture would be repeated one and a half times across the building. If the number entered was 128, then half the texture would be rendered.
The same calculation applies for repeating textures in the Y (up) and Z directions. For most sections of the building, only one texture ratio is used to determine how the texture is handled, but for some two ratios are needed (for example, textureIndexRoofX and textureIndexRoofZ, determine how many times the single roof texture is repeated in the X and Z directions).

Many of the attributes for a flat roofed building are used throughout the other generic buildings; the flat roofed rectangular building is the simplest of the generic buildings.

Rectangular Building: Peaked Roof

<RectangularBuilding       roofType="PEAKED"       sizeX="44"       sizeZ="44"       sizeBottomY="5"       textureIndexBottomX="512"       textureIndexBottomZ="512"       sizeWindowY="225"       textureIndexWindowX="768"       textureIndexWindowY="384"       textureIndexWindowZ="768"       sizeTopY="5"       textureIndexTopX="512"       textureIndexTopZ="512"       textureIndexRoofX="256"       textureIndexRoofZ="256"       sizeRoofY="45"       textureIndexRoofY="256"/>

Beacon

This element is used to add a beacon to the scene.  Beacons can be added as stand-alone objects, but are usually added as objects attached to control towers.  This element is not allowed to contain other data and must be terminated with "/>".

<Beacon       type="CIVILIAN"       baseType="AIRPORT" />

type Type of beacon CIVILIAN
MILITARY
baseType Type of facility AIRPORT

AttachedObject

This element is used to attach another object to a scenery object.  At this time only LibraryObject elements can be used as a base for attaching objects.  When attaching an object, an optional BiasXYZ can be applied.  Also, a rotation around the pitch, bank or heading axis can be applied to the attached object.  This element is allowed to contain RandomAttach, Bias, Beacon, Effect and LibraryObject data, which must occur in that order (though all are optional) and should not be terminated with "/>".

Attached objects are subject to any rotations or displacements applied to the base object, or any animated parts.  Refer to the Using Modeling Tools documentation and the Library Objects table for more information about attach points. Nesting of attached objects is supported but is not encouraged (for example, a library object can be placed that has a control tower attached to it and the attached control tower has a beacon attached to it).

The following example attaches a beacon to a metal tower.

<SceneryObject       lat="31.95451772"       lon="-89.23370500"       alt="0F"       altitudeIsAgl="TRUE"       pitch="0"       bank="0"       heading="162"       imageComplexity="VERY_SPARSE" >       <LibraryObject             name="GUID"             scale="1.0" />       <AttachedObject             attachpointName="attachpt_beacon"             pitch="0"             bank="0"             heading="0">             <Beacon                  type="CIVILIAN"                  baseType="AIRPORT"/>       </AttachedObject> </SceneryObject>

attachpointName Name of attach point in model (refer to the Using Modeling Tools documentation on the Attach tool). String
instanceId Optional GUID that identifies this instance of the attached object. GUID in the format:
{nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
pitch Pitch applied to object 0.0 to 360.0 floating point value
bank Bank applied to object 0.0 to 360.0 floating point value
heading Heading applied to object 0.0 to 360.0 floating point value

RandomAttach

This element is used to apply some randomness to AttachedObject elements. This element cannot contain other elements.

<RandomAttach       randomness="LOCATION_RANDOM"       probability="0.5" />

randomness When the attached object is to appear. LOCATION_RANDOM will generate a random number based on the location, so will always be the same. PURE_RANDOM will generate a new random each time the section of scenery is created. ALWAYS_DISPLAY
LOCATION_RANDOM
PURE_RANDOM
probability The probability of the attached object appearing. 0.0 to 1.0

ModelData

This element is used to create a .BGL file that contains model data for one or more newly created library objects.  Library object models are created with Modeling Tools, and those models can be made part of a scenery .BGL file.  ModelData is not a sub element of SceneryObject, it is used at the same level as SceneryObject. The GUID set as a file property when creating the model is used by the compiler to identify the correct model. If the reference to a model is made in the same XML placement file as the model's position, then that model will not be available worldwide, but will be scoped to the vicinity of the placement (this is for scenery optimization purposes). If the aim is to create a library of models that each have worldwide scope, then create an XML file containing only the ModelData references, and then use additional XML placement files to actually place the models at their various locations. Compile these XML files into BGL, and place the BGL files in the Addon Scenery/scenery folder. For an example of this use of ModelData, refer also to the tutorial in the Autogen documentation. This element is not allowed to contain other data and must be terminated with "/>".

<SceneryObject instanceId="{GUID}"       lat="47 25.89"       lon="-122 18.43"       alt="0"       pitch="0"       bank="0"       heading="0"       altitudeIsAgl="TRUE"       imageComplexity="NORMAL">       <LibraryObject name="{GUID of model}"             scale="1.0" /> </SceneryObject> <ModelData       sourceFile="testx.MDL" />

sourceFile Name of file to look for model data in. Required. If this attribute refers to a relative path, the base path is assumed to be the directory containing the source .XML file. String
fileOffset Offset into file to look for model data. Optional. Non-negative integer

ExclusionRectangle

This element is used to create an exclusion region for scenery.  Exclusion rectangles are used to remove scenery objects from the specified region.   Flags can be used to exclude a subset of objects in the specified region. This element is not allowed to contain other data and must be terminated with "/>". Runways and associated objects such as PAPI lights (see Facility Data), and aircraft, are not excluded using this mechanism. Use ExclusionRectangle to exclude Beacons, Effects, ExtrusionBridges, GenericBuildings, LibraryObjects, Taxiway signs, Triggers and Windsocks only.

Note that if excludeAllObjects is set to true all scenery objects will be excluded, but not any objects (notably trees) created and placed by Autogen. To exclude autogen refer to the Terrain and Scenery documentation (the section on the Shp2Vec tool).

The following example will exclude all the scenery objects around Seattle-Tacoma airport, except the generic buildings, which will be rendered.

<ExclusionRectangle       latitudeMinimum = "N47.0"       latitudeMaximum = "N48.0"       longitudeMinimum = "W123.0"       longitudeMaximum = "W122.0"       excludeAllObjects = "FALSE"       excludeBeaconObjects = "TRUE"       excludeEffectObjects = "TRUE"       excludeExtrusionBridgeObjects = "TRUE"       excludeGenericBuildingObjects = "FALSE"       excludeLibraryObjects = "TRUE"       excludeTaxiwaySignObjects = "TRUE"       excludeTriggerObjects = "TRUE"       excludeWindsockObjects = "TRUE"/>

ExtrusionBridge

ExtrusionBridge elements contain one and only one AltitudeSampleLocationList, one and only one PolylinePointList, one optional PolylineObjectPlacementList, and one optional BankShearList element. Note that these elements must be entered in the order shown.

<ExtrusionBridge       instanceId = "GUID"       probability = "0.5"       suppressPlatform = "FALSE"       imageComplexity = "NORMAL"       roadWidth = "12"       extrusionProfile = "GUID"       materialSet = "GUID">       <AtitudeSampleLocationList />

      <PolylinePointList />       <PolylineObjectPlacementList />       <BankShearList /> </ExtrusionBridge>

instanceId Optional GUID identifying this instance of an ExtrusionBridge object. GUID in the format:
{nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
probability A random seed value. All extrusion bridges with the same value will use the same visual representation (girders, pylons, lanes, etc.). 0.0 to 1.0
suppressPlatform Setting this value to true will prevent any moving objects on the bridge. The platform is an artificial platform and is not rendered. Suppressing the platform can improve performance. TRUE or FALSE
imageComplexity Minimum image complexity setting for the objects to appear. For example, objects set at NORMAL will appear if the setting is DENSE, but not appear if the setting is SPARSE. VERY_SPARSE
SPARSE
NORMAL
DENSE
VERY_DENSE
roadWidth Width in meters. Do not set this value to zero, this can cause the compiler to crash. Non-negative floating point value.
extrusionProfile GUID of profile in Extrusions.xml. GUID in the format:
{nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
materialSet GUID of materials in Materials.xml. GUID in the format:
{nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}

The Golden Gate bridge, shown in the first image below, is not an extrusion bridge, but a specific library object created by an artist. Extrusion bridges, such as the one shown in the second image below, are simple gantry type bridges without towers, suspension cables, or any specific recognizable features. There are around 55,000 extrusion bridges in ESP, whereas there is only a small number of specifically created recognizable bridges. Both types of bridge can take moving traffic, this is set by vector data (described in the Terrain and Scenery documentation) though both require platforms to elevate the level of the traffic above the surface of the water. For library objects, the platform is set in the model (see the notes for the Attach Point Tool in Using Modeling Tools) and for extrusion bridges the platform is defined in extrusions.xml. Extrusion bridges can be excluded by use of the ExclusionRectangle element. Also, the rendering of these bridges in the simulation is sensitive to the Scenery Complexity slider, not the Autogen Slider, nor Autogen exclusion mechanisms.

The information entered in the XML for the BGL compiler is referenced in the Extrusions.xml file. The following table shows the entries that should be made for an extrusion bridge in extrusions.xml.

Extrusion id GUID identifying this type of extrusion bridge. This will be the value set in extrusionProfile attribute. <Extrusion id="{55959300-bb2d-4b75-8d6a-934a0fe8f777}">
FriendlyName This string is mainly for easy identification of the extrusion, but is also used in the Config editor tools described in the autogen documentation. <FriendlyName>RailRoad Bridge Double Girder 1</FriendlyName>
PointList Defines a cross-section of the bridge, in meters, as pairs of floating point values. Typically the first two entries define the width of the bridge deck, relative to the centerline.
In the example given, the bridge deck is 12m wide, defined by Point 0 and Point 1, and there is a guard rail, defined by Point 2 and Point 3, and a drop down section that basically will cover the top of the pillars, defined by Points 4 to 7.
  <Point>-6.000,0.000</Point>
  <Point>6.000,0.000</Point>
  <Point>-6.000,1.000</Point>
  <Point>6.000,1.000</Point>
  <Point>5.500,0.000</Point>
  <Point>5.500,-2.000</Point>
  <Point>-5.500,0.010</Point>
  <Point>-5.500,-2.000</Point>
ExtrusionSegmentList List of ExtrusionSegments.  
ExtrusionSegment Contains information pertaining to various pairs in the PointList.  
PointIndices Pair of Points that define this segment. The bridge deck in this example. <PointIndices>0,1</PointIndices>
MaterialIndex The reference number of the material to use, in a list of materials defined by the materialSet attribute. The example will point to the second material in the list, which is indexed from zero. <MaterialIndex>1</MaterialIndex>
TextureWidth The material texture will be tiled along the length of the extrusion, each tile being this long in meters, 30 meters in the example. <TextureWidth>30.000</TextureWidth>
TextureVExtents These two floating point values are references into the material texture. If they number from 0.0 to 1.0, that is the segment of the texture to use (from 7/8ths of the width of the texture, to the full width, in the example). These entries can be greater than 1.0. For example values of 0.0, 2.0 will mean that the entire texture is repeated twice across the width of the segment (perhaps repeating road markings twice across the width of a bridge deck).
Note that using numbers greater than 1.0 is costly in performance.
<TextureVExtents>0.875,1.000</TextureVExtents>
ExtrusionPlatformSegmentList A list of ExtrusionPlatformSegments  
ExtrusionPlatformSegments Contains bridge specific information defining the actual platform traffic will use.  
PointIndices A pair from the PointList that are to be used as a platform. Clearly these are the points that define the bridge deck. <PointIndices>0,1</PointIndices>
SurfaceType One entry from the list of surfaces defined for a Runway entry. These do not affect the appearance of the bridge surface, but do affect special effects (such as on a dirt road) and traffic sounds. <SurfaceType>PLANKS</SurfaceType>

AltitudeSampleLocationList

This element is part of an ExtrusionBridge element. AltitudeSampleLocationList elements contains exactly two AltitudeSampleLocation elements,

<AltitudeSampleLocationList>       <!-- AltitudeSampleLocation elements --> </AltitudeSampleLocationList>

alt Altitude Any floating point value. Altitude denotes the vertical displacement of the PolylinePoint from the plane defined by a line segment connecting the terrain at the two AltitudeSampleLocations and a constant elevation line perpendicular to that segment. The intention is to establish the vertical profile of the bridge deck. Altitude may be suffixed by 'M' or 'F' to designate meters or feet. Default is meters.

BankShearList (reserved for future use)

This element is part of an ExtrusionBridge element. BankShearList must be empty or contain one BankShearEntry element for each PolylinePoint element present in the PolylinePointList.

<BankShearList>       <!-- Two or more BankShearEntry elements --> </BankShearList>

These elements form part of a BankShearList.

<BankShearEntry       bank = "-15.0"/>

bank The bank angle of one section of the bridge. -180.0 to 180.0

Facility Data

Facility data is also placed inside of <FSData> elements.  The following is a list of the valid facility types and a description of each.  The facility data uses references to standard region codes and airline codes.  Information on facility codes can be found on the web site for the ICAO organization (www.icao.org, specifically, Document 7910 Location Indicators).  Alternative sources may also be available via the Internet.

Airport

This element is used to indicate the placement of airport facility information.  Airports are placed according to their airport reference point and may contain a large amount of data.  When adding Taxi information to an airport, the following elements must all be present and appear in this order: TaxiwayPoint, TaxiwayParking, TaxiName, TaxiwayPath. This element is also allowed to contain Tower, Services, Com, Runway, RunwayAlias, Aprons, ApronEdgeLights, TaxiwaySign, Waypoint, Approach, Ndb, Helipad, Start, Jetway, BlastFence, BoundaryFence, DeleteAirport data and should not be terminated with "/>".

Jetway

Jetway elements are part of an airport, and must contain one, and only one, SceneryObject element. One jetway can service at most one parking spot. A jetway will animate (move towards the main exit) when the user presses Ctrl-J and will usually come in to the main exit on the left side of the aircraft. AI controlled aircraft will also trigger the animation of the jetway. To replace jetways at an airport, use the DeleteAirport element with the deleteAllJetways field set to "TRUE", then enter the new jetway elements. Note that all parking spots do not require jetways. Refer also the Jetways modeling document.

<Jetway       gateName = "GATE_A"       parkingNumber = "1" >       <!-- Scenery object --> </Jetway>

parkingNumber Both a gateName and parkingNumber are required to uniquely identify a parking location. Non-negative integer.

BlastFence, BoundaryFence

BlastFence and BoundaryFence elements are part of an airport, and must contain at least two Vertex elements. To replace fences at an airport, use the DeleteAirport element with the deleteAllBlastFences or deleteAllBoundaryFences fields set to "TRUE", then enter the new fence elements.

<BlastFence>       instanceId = "GUID"       profile = "GUID" >       <!-- Two or more Vertex elements --> </BlastFence>

For example:

<BoundaryFence instanceId="{guid}" profile="{guid}" >        <Vertex lat="56.95721658" lon="-158.63880255" />        <Vertex lat="56.95649892" lon="-158.64139507" />        <Vertex lat="56.95643874" lon="-158.64143179" />        <Vertex lat="56.95638593" lon="-158.64147906" />        <Vertex lat="56.95634419" lon="-158.64152952" />        <Vertex lat="56.95617823" lon="-158.64175382" />        <Vertex lat="56.95362527" lon="-158.63877271" />        <Vertex lat="56.95253646" lon="-158.64211307" />        <Vertex lat="56.96425872" lon="-158.65580206" /> </BoundaryFence>

instanceId Optional GUID identifying this element. GUID in the format:
{nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
profile Required, a GUID identifying the type of fence from the Extrusions.xml file. GUID in the format:
{nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}
The boundary fence at Boeing Field is just visible underneath the wing of the aircraft.

There are two relevant entries in the extrusions.xml for each blast or boundary fence. In a section Extrusions.Fences there is an entry with the following attributes:

FenceProfile id This is the GUID that matches the profile attribute. <FenceProfile id="{02D65B05-F752-47a3-83AF-D570243EB3EE}">
FriendlyName A description of the fence, also used by the Autogen Config editor tools. <FriendlyName>5 Meter Chain-link</FriendlyName>
MaterialSetReference GUID of the material to use, defined in the Materials.xml file. <MaterialSetReference>{2D6ED02C-51CF-43D2-9EBD-A5E86284830B}</MaterialSetReference>
ExtrusionReference GUID internal to the extrusions.xml file, identifying the key physical attributes of the fence, described in the following table. <ExtrusionReference>{9093AC0C-FB5E-433D-9E2B-C19D637EA664}</ExtrusionReference>

The Extrusion entry in Extrusions.xml contains the following entries for each fence:

Extrusion id GUID identifying this type of extrusion fence. This will be the value set in the ExtrusionReference attribute. <Extrusion id="{9093AC0C-FB5E-433d-9E2B-C19D637EA664}">
FriendlyName This string is mainly for easy identification of the extrusion. <FriendlyName>Fence vertical 2 meter extrusion</FriendlyName>
PointList Defines a cross-section of the fence, in meters, as pairs of floating point values.
<Point>0.000,0.000</Point>
<Point>0.000,2.000</Point>
ExtrusionSegmentList List of ExtrusionSegments.  
ExtrusionSegment Contains information pertaining to various pairs in the PointList.  
PointIndices Pair of Points that define this segment. For a fence this is usually just points 0 and 1. <PointIndices>0,1</PointIndices>
TextureWidth The texture width typically matches the height of the fence. <TextureWidth>2.000</TextureWidth>
TextureVExtents These two floating point values are references into the material texture. If they number from 0.0 to 1.0, that is the segment of the texture to use (the full width of the texture, in the example). These entries can be greater than 1.0. For example values of 0.0, 2.0 will mean that the entire texture is repeated twice up the height of the fence.
Note that using numbers greater than 1.0 is costly in performance.
<TextureVExtents>0.000,1.000</TextureVExtents>

DeleteAirport

This element is used to delete an airport or part of an airport and potentially replace with new information.  This element is not allowed to contain other data and must be terminated with "/>".

<DeleteAirport       deleteAllApproaches = "TRUE"       deleteAllApronLights = "TRUE"       deleteAllAprons = "TRUE"       deleteAllFrequencies = "TRUE"       deleteAllHelipads = "TRUE"       deleteAllRunways = "TRUE"       deleteAllStarts = "TRUE"       deleteAllTaxiways = "TRUE"       deleteAllBlastFences = "TRUE"       deleteAllBoundaryFences = "TRUE"       deleteAllControlTowers = "TRUE"       deleteAllJetways = "TRUE"/>

For example, to replace all the jetways at an airport with a new model, enter the following code:

<Airport       region="North America"       country="United States"       state="Illinois"       city="Peru"       name="Illinois Valley Regional"       lat="41.35186742"       lon="-89.15308328"       alt="199.33918762"       magvar="0.0"       ident="KVYS">            <DeleteAirport           deleteAllJetways = "TRUE"/>        <Jetway           gateName = "GATE_A"           parkingNumber = "1" >           <!-- Scenery object -->       </Jetway>        <Jetway           gateName = "GATE_B"           parkingNumber = "1" >           <!-- Scenery object -->       </Jetway>        // Add as many Jetway elements as needed   </Airport>

Note

The meaning of each 2-letter approach leg code is defined in the 424-16 specification document maintained by ARINC Incorporated and is a standard used in navigation databases and flight management systems from companies such as Jeppesen and Rockwell Collins. You can order the complete specification, which includes complete definitions and illustrations of each let type, from the ARINC web site: https://www.arinc.com/cf/store/catalog.cfm?prod_group_id=1&category_group_id=1.

DmeArc

This element is used to add a DME ARC to an approach transition.  This element is not allowed to contain other data and must be terminated with "/>".

<DmeArc       radial="11"                       distance="999"                  dmeRegion="K9"                  dmeIdent="IDENT"/>

TransitionLegs

This element is used to signify the legs that are used in a Transition.  TransitionLegs have no attributes and are used as a container to hold a list of Leg elements.  The Leg elements describe the individual segments of the transition.

<TransitionLegs>       <!-- add Legs elements here --> </TransitionLegs>

TaxiwayPoint

This element is used to add a point to the taxiway network for routing on the ground.  Since the network will contain many taxiway points (and possibly parking spots), each of these locations need to have an "index" that uniquely identifies a point when building the network. There are two ways to specify the position of the point.  The first is to use a lat/lon pair that will give the exact coordinate.  The second is to use a biasX/biasZ pair that specifies the displacement of the point from the airport reference point.   This element is not allowed to contain other data and must be terminated with "/>". 

<TaxiwayPoint       index="0"           type="NORMAL"                        orientation="FORWARD"       biasX="-624.169006"         biasZ="-692.226013"/>                <TaxiwayPoint       index="1"         type="HOLD_SHORT"           lon="10.234"            lat="65.299"/> <TaxiwayPoint       index="2"          type="NORMAL"       biasX="-552.966980"        biasZ="-775.700012"/>

index Identifier assigned to this taxiway point to make it unique inside of an airport. This identifier must be unique for all TaxiwayPoint and TaxiwayParking locations inside of an Airport. Valid integer range is 0 to 3999.

Format can be decimal or degrees-minutes-seconds
biasX Bias from airport reference point. Default units are meters. Floating point value
biasZ Bias from airport reference point. Default units are meters. Floating point value

TaxiwayParking

This element is used to add a parking spot to the taxiway network.  Taxiway parking spots can have preferred airline designations.  Since the network will contain many taxiway points (and possibly parking spots), each of these locations need to have an index that uniquely identifies a point when building the network. There are two ways to specify the position of the parking spot.  The first is to use a lat/lon pair that will give the exact coordinate.  The second is to use a biasX/biasZ pair that specifies the displacement of the parking space from the airport reference point.  

The size of a parking spot required for an aircraft is taken from the wingspan of the aircraft recorded in the Aircraft Configuration Files. The wingspan is converted to meters and rounded up. Also refer to the Traffic Toolboxdocument (the Dump Airport List tool will provide details on all airports and the sizes of the parking spots available) and the fs10.AircraftTypes.csv document, which lists all the types of aircraft that can appear as AI controlled aircraft and the radius of parking spot required for them.

This element is not allowed to contain other data and must be terminated with "/>".

airlineCodes (optional) Comma separated list of airline codes that can use this parking spot. This text should match the strings entered for the atc_parking_codes entry in the aircraft configuration file. To maintain compatibility, the ICAO names for airlines should be used.
pushBack The behaviour of parking pushback is to pushback the aircraft either one wingspan radius, or to the first taxiway node, whichever comes first, do a 180 degree turn, and then proceed along the taxiways. There is no control over which way the aircraft will turn the 180 degrees, but if the pushback of one radius is too far, entering a taxiway node closer to the parking area will shorten the pushback distance. The settings for this attribute have not been implemented. NONE, BOTH, LEFT and RIGHT are not implemented.

Services

This element is used to add services to an airport.  There are no attributes that can be applied to the Services element.  This element is allowed to contain Fuel data and should not be terminated with "/>".

<Services>       <!-- Add service information here --> </Services>

TaxiwaySign

This element is used to add a taxiway sign. It is not allowed to contain other data and must be terminated with "/>".  The following XML will create a taxiway sign near the normal runway start point of Seattle-Tacoma airport:

<TaxiwaySign       lat="N47 25.91"       lon="W122 18.50"       heading="0"       label="l[G]d[F\]m[11R-29L]"       size="SIZE5"       justification="LEFT"/>

The key to the text of the taxiway sign is the format of the label. There are six types of sign, each identified by a single lower-case letter:

l Location Yellow text on black
d Direction Black text on yellow
m Mandatory White text on red
i Information Black text on white
r Runway White text on red
u Unknown Black text on white

The following characters describe the content of the sign. The characters can be any upper case letter (A-Z), any numerical digit (0-9), or any one of the following special characters:

_ or space Space
- Dash
> (or >) Right arrow
^ Up arrow
' (apostrophe, or &apos;) Up-right arrow
< (or <) Left arrow
v Back arrow
` (backwards apostrophe) Up-left arrow
/ Back-left arrow
\ Back-right arrow
[ Left border
] Right border
x Do not enter
# ILS boundary
= Runway boundary
. Dot
| Vertical line

The following example creates a location sign for taxi "golf":

l[G]
This example creates a location sign indicating you are on taxiway "alpha-echo":

l[AE]

Note the brackets. These create the black outline around the letter on location signs. If you omit the brackets the letter will have a black line above and below it but not on either end. You can also use brackets on direction and runway signs to increase the spacing at either end of the segment.

Direction signs are made up of a combination of directional arrows and taxiway and runway designators. Arrows can appear before or after the taxiway or runway designator. All of the following are valid direction signs:

d/G
dG/
d/G/

Using these components you can create signs of arbitrary complexity. For instance, the following example sign will tell a pilot that they are located on taxiway Golf at the intersection with runway 11R/29L and that taxiway Foxtrot is back and to their right:

l[G]d[F\]m[11R-29L]

lat Latitude -90 to +90 degrees
Format can be decimal or degrees-minutes-seconds
lon Longitude -180 to +180 degrees
Format can be decimal or degrees-minutes-seconds
heading Heading in degrees of the sign. Note that this is the heading of the sign, the text will face 90 degrees clockwise from this heading. 0.0 to 360.0 floating point value.
label Label string (see the description above). Formatted string.
justification (optional) Right or left justify the text. (default is LEFT) LEFT or RIGHT
size Size of the sign. One of five fixed options: SIZE5 is the largest, SIZE1 is the smallest. SIZE1 to SIZE5

Using the BGLScan Tool

A new utility has been created to check the integrity of the scenery databases.  This tool will catch errors related to library object placements and generate other general statistics.  The tool is intended to be run from a root directory that contains all of the scenery available to the application.  BGLScan has no knowledge of Scenery.CFG files so it looks at all .BGL files present below the specified root directory even if those files are not part of an active scenery area.  Because BGLScan attempts to resolve linkages between library objects and their placements, running on a subset of the scenery will likely result in many false positives.  The tool also validates the textures referenced by models embedded within the BGL file -- using the functionality of the MDLScan tool (which can be used independently to validate .MDL files). Since there is no GUI for this tool and it can generate a large report, it is recommended that the output be sent to a file for viewing after a scan is completed.  The output of the tool can be divided into several sections:

Report of the number of objects. General statistics on the number of objects of each type that were found in the database.
Report of duplicate objects. Multiple library objects that have the same GUID can cause confusion when loading models and should be remedied.
Report of missing objects.  These are library object models that are not present in the scenery scanned, but there is a placement requesting such a library object.  An example would be a placement of a custom building using the BGLComp SDK, but no art is present for that building.
Report of unreferenced objects.  These are library object models that are present in the .BGL files, but not referenced by a scenery placement.  In the case of the stock scenery there will be several models listed as these models are shipping for backwards compatibility to satisfy potential placements in add-on scenery.  If unreferenced objects are found in an add-on scenery area a message is output that the model can be safely removed, to save space.
