Is it possible to exclude an object from being reflected in an object that has reflectivity without having multiple renders? Also, is it possible for an object to reflect another object that is in another layer without actually rendering that object outside of the reflection (also without having multiple renders)?
The idea is that there could be a mirror and two characters. Character 1 looks into the mirror and sees Character 2 and the room around him, but not his own reflection. When he looks around the room he cannot see Character 2 anywhere other than in the mirror.
This could be done with multiple renders, but it would be interesting if it didn’t need to.
