I added a DepthMask material to a plane and cube and saw that it was able to "pass through" video over any AR rendered images, which is what I wanted. But when I did this for a complex 3d model (imported fbx), my 3D object drew on the screen like normal, just as a video pass-through mask. Are there limitations to what DepthMask can be applied to?
I want to show cutaways of 3D objects, and have a 3D mask on the parts that aren't AR so that will block the rendered parts when in front of them.
I'm using Unity 4.1.2
Apologies if this has already been covered, I read several entries about Depth masking, but they involved putting the mask object under ARCamera, but I need it under the target I believe. I'm also not sure if this is more of a Unity question.
