Today I came across the impossibility to copy the Reflectance channel from one Material to another. It is also not possible to edit multiple identical Reflectance channels together.
Wouldn't it be great if C4D includes what I call a Cascading Materials system!
Let me explain:
Materials can refer to 'parent materials' from which they copy certain channels.
This can result in a very intelligent 'tree' of related materials, more or less like css in html.
The top Materials define e.g. Reflectance and Normal, while the children define Color. In this way several objects with different Color Textures (e.g. a book or magazines pages), can refer to the same Relectance and Normal maps (the structure of the paper), while they differ in Color Texture (the printed layouts of the pages)
