AFAIK, ERC won't work on material values, but I could be wrong. The code for shaders doesn't look like it would work with ERC, so I've never tried it. I haven't tried pz3s, but I assume anything you can do in a cr2 could also be done in a pz3. I know you can use ERC on light parameters or pretty much anything else that has a parameter dial. I usually work with F node in preference to using keyframe animation of materials (because keyframe animation isn't saved to the library when you save a material) so I haven't looked at what happens to the code in a keyframe animated material saved in a pz3. If there is anything resembling a parameter dial in the keyframe setup, then maybe ERC will work. My gut feeling is not.
