Here is a nice tip from Mario Tran Phuc, who shows that you can create a system for linking textures in C4D. You can easily set up a link between Cinema 4D textures and Cycles 4D materials.
You can easily pass texture information from the Cinema 4D Material editor to a Cycles 4D object material. You can download the scene file over at the Cycles 4D Forum.
Cycles 4D has a node based material system, but that doesn’t mean that you can’t sync linking textures from a native C4D shader to Cycles.
Cycles is an unbiased GPU/CPU render engine developed by the Blender Foundation and made available under the Apache 2 licensing system. Cycles 4D is a dedicated bridge plugin allowing Cinema 4D users to access the Cycles rendering engine directly inside Cinema 4D without the need for an external application.
