I am trying to isolate the reflection and refraction contribution of an object separately using LPE. How can I do this?
I added LPE tag to my object at the HDA level which has a geometry subnet inside. So I added a tag there too but no matter what combination of this I try, I get a blank image pass:
lpe:C<RG>.*+<O.'object'>
My object is phantom though, not sure if that matters.
Thanks in advance.
