The Pixel Lab - 340+ Procedural Material Pack for Cinema 4D
LIB4D | R16+ | Shaders | Textures | 10 JPG Renders | 13.5 MB

Best of all we are only asking $45 for the pack, which should make it very accessible to everyone.

Please note that: it will only work in R16 and above because of the new Reflectance channel which is used heavily.
