ID masks for reflections Is there a way to get ID masks or otherwise isolate an objects reflection in the compositor? For example, if I have a sphere above a reflective plane, I can set an ID mask on the sphere and use that to manipulate it in the compositor. But then the reflection will no longer be accurate. If I want to do the same manipulation on the reflection, I have no way to get it.
You can use Glossy Pass both in Compositing and Shading

Compositing









Shading

You can apply a Light Path Node to the Sphere Material:
