Project Acoustics Unity Bake Overview

This article gives a brief overview of how to create an acoustics bake for a scene in Unity.

Open the Project Acoustics editor mode

Import the Project Acoustics plugin package to your project. For help with this, see the Unity Integration pages for Unity. Once the plugin is integrated, open the Acoustics UI by selecting the Acoustics item from the Window menu.

Acoustics Mode and tabs

The four steps to doing a bake are separated into four tabs: Objects, Materials, Probes, Bake

1. Objects

Tag all the objects you want included in the acoustic simulation as Acoustics Geometry. Tag your navigation mesh or floor objects as Acoustics Navigation to indicate where the player can move in a level.

See the Objects page for more details

Unity objects tab

2. Materials

For each of the materials that have been tagged as Acoustics Geometry, assign an acoustic material that defines how reflective or absorbent that material should sound.

See the Materials page for more details

Unity materials tab

3. Probes

Specific your simulation resolution, file names and paths, and then start the probe placement and voxel Calculation. This should take a few seconds to a few minutes, depending on the size of scene and the simulation resolution. Once completed, preview the voxels and probes in the scene to make sure you have the coverage you expect.

See the Probes page for more details

Unity probes tab

4. Bake

Once you've verified the probes and voxels, you can fill in your Azure credentials and submit a bake. You can also start a local bake as well (takes much longer).
