Sorry to put this as a reply I’m not very good with forums 🙁
Anyways I’m updating this question, I tried restarting Cinema 4d and it works fine. Now I’m just curious how to copy a material channel from one material to another. I have an awesome skin material from another scene and I want to copy the luminance channel to the new materials to take advantage of the subsurface scattering. I would really hate to do it from scratch as I don’t remember all the values and I want the model to be even. Thanks!
