SilverWing shows how to create scratched and worn edges With Octane using dirt or Ambient Occlusion.
Most render engines will allow you to work procedurally, and some things are pretty much the same no matter where you are. One of the things is creating worn edges using nodes. With some renderers, it’s using a dirt map, but with Octane and others, it’s using an Ambient Occlusion to isolate those edges. Silverwing’s (Raphael Rau) shows how this works in Octane using Cinema 4D.
“In this tutorial, you will get a basic overview of how you can create worn edges and dirt with a variation using Octanes Dirt (Ambient Occlusion) or Vertex Maps,” Rau says. The techniques in the video work best with the newer 2018 version of Octane.
Although creating worn edges relies on the same concept, there are different ways to get there. For instance, you can use vertex maps in Cinema 4D to achieve the same effect.
