I'm following along with this tutorial https://www.youtube.com/watch?v=NnlaIizA_AQ&t=552s

He uses nodes to get the edge wear effect, but how do I achieve more control over this? Such as edge wearing only certain edges.

Is there a way to use vertex groups instead of a shader that auto detects edges? Or use the bevel shader and use a vertex group to control the influence.

Just create two materials.

As with all materials you can select the vertices on your object where you want to put your material on and the hit "assign".

  • $\begingroup$ That's going to create some hard transitions. I would like to have one edge worn and then fade out towards the adjacent edges. $\endgroup$
