You’ve probably seen that abbreviation around the interwebs and wondered. Well, C4DtoA is the official name for the Arnold Renderer plugin for C4D. C4DtoA has had a blazing fast development speed thanks to its amazing development team and leadership. When they added a curvature map some time ago, I made sure I put a note in Google Keep to do a tutorial on it. It is a fantastic map that I am constantly finding new uses for. I hope you have fun getting your curvature on!
Curvature Map? What is that?
Sounds saucy, right? Well, a curvature map analyzes the normals of the geometry returning different values for areas that are convex or concave. I’m no scientist, but they are cool, trust me.
