Hi everyone,
I am trying since a while to program a simple app in unity but I faced many problems, mainly 2 still appearing,
First, I import urdf robot model and once I run my app on the hololens2 the object directly falls down and diseappear.

Second, I try to position an object using vuforia marker or image target, when I scan the marker the object seems to fly in a different far position each time.
can you help in this issues??
Thanks

    Hello, Welcome to Microsoft Q&A,

    It seems like the RigidBody component has been added to your 3D model object. It will control the position of the object through physics simulation, such as pulling downward the object by gravity or reacting to collisions with incoming objects. So please remove the RigidBody component and try again. For more information please see: Rigidbody

    For your second question, it seems like there is a race condition because the RigidBody component and Vuforia make transform operations on the 3D model object at the same time. If the issue still happened after you remove the RigidBody component, please open a new question in Q&A.
