Hello,
I created a folder with the C# method and the 3d object scene layers become visible. Only the 3D object scene layers that contain textures glitch a lot on my Quest 2 VR headset. 3D object scene layers without textures do not glitch. I also exported as test a building (multipatch) from a 3D object scene layer as an OBJ file from ArcGIS Pro and when I import it directly into Unity, the textures of the building look perfect and do not glitch in my headset.
What can I do about this?
I saw in the plugin's render script that, for example, Mipmaps are generated. So that doesn't seem to be the problem. When I zoom out in the Unity Editor I also see that textures are replaced by smaller versions so that seems good too.
