I'm trying to make a mask around the edges of the metal circles to look shiny wail having the wrest of the faces black/dark grey. So what I did was use the Input>Geometry and then use converter>ColorRamp (Color Ramp) to clamp the values together to get the edge to show up. No matter how I put it, it wont work... There shouldn't be wrong I'm doing I dont think, I'm following the exact instructions shown on a tutorial on the exact same thing Link: https://www.youtube.com/watch?v=lYseMQDkPAI If someone knows what the problem is please help me
As shown in the manual: Geometry Node — Blender Manual:
An approximation of the curvature of the mesh per vertex. Lighter values indicate convex angles, darker values indicate concave angles. It allows you to do effects like dirt maps and wear-off effects.
Pointiness being a Cycles Only feature, you have to be in render shading and using Cycles render engine to see it. The material view is powered by Eevee render engine, hence you can't see it there either.
