Three Ways to Use the Arnold Curvature Map
First off, what the heck is C4DtoA?
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.
What You Will Learn:
- A fairly decent explanation of the Arnold Curvature Map
- How to use the Curvature Map to create a cool ceramic shader
- How to use the Curvature Map to add wear/tear to your objects
- How to use the Curvature Map to add a rounded edges look
Tools You’ll Need:
- C4D R17 – Mac or PC (Arnold runs on BOTH)
- Solid Angle’s Arnold Render (watermarked demo here)
- Coffee and a comfy chair.
