excluding geo from occlusion?

[tashko.zashev]

Question: I have a scene that uses geo caches. When I apply the above method on the mesh with no cache applied it works fine. But as soon as I apply the cache it fails. I think this must have to do with the user attribute on the mesh not being recognized with the geo cache. However, when I look at the geo itself it does still have that user attribute there, it just is not being read by the cache apparently. Is there any way to resolve this?

Thanks for the file.
You need to add another user attributes to the deformed shape and it will work even with referenced geometric (geo cache applied)
Have attached an example:

So I tried this, and it worked on a piece of geometry (with polygons) but it didn't work with a vray rectangle light.
Any reason a light should act differently?

Doesn't work with lights at the moment, maybe we can add this as a feature request.
