Learn how to set up an advanced node shader group with this tutorial by Lawrence Jaeger.
I often create shaders that use the Pointiness attribute, followed by a Color Ramp to create a sort of edge map. I love it so much! The problem I kept running into was when I wanted to package my shader into a neat node group. I had no control over that edge map without having to dive into the node, find the Color Ramp and adjust the handles. So I looked online for a solution but found nothing that I liked. So I fiddled around until I came up with this solution. Let’s get into making the setup!
