Hiding transmissible materials from emitters
Posted: Wed May 11, 2011 1:26 am
Hi again.
If a scene has more than one light source can you hide an object from one emitter and reveal it to the other?
For example a tinted glass object in a scene with Physical Sky and a light emitter.
It looks much better when lit by HDRI or Sky.
Now add a small emitter to the scene e.g a Camera Light and the object reflects
terrible noise from the surface.
I know you can solve this with compositing two versions of the image one lit by one emitter and
one lit by the sky. But then that removes the nice light reflections..etc
So is there a way to be selective about which emitters/light sources your object will respond to?
