I would like to use the intersection filters with scenes with many instances.
but how I have to set them? I tried to set them with geomID in the base geometry like without instancing. but it doesn't work.
I tried setting them in the top level scene with the instance ID but again no luck...
any hints on how to set them in a right way?
If you have a toplevel scene, with multiple instanced scenes, then you have to set the intersection filter for the geometries inside the instanced scene. You cannot set the intersection filter to the entire instance in the toplevel scene.
