Blender 2.8 - Edges, dust and rust.

Then I have made a new tutorial on how you use the Blender 2.8 "Bevel" & "Ambient Occlusion" Nodes to created Edges, dust and rust.

Even easier than using the "Pointiness" node and with better result,

Enjoy :)!

My real name is Joakim Tornhill, but most people know me as "Blender Insight"... the procedural node & material guy :). I love how Blender can turn a simple sphere in to a photo realistic cherry, orange, planet or football....without using any external sources like images at all. That is amazing! However, I can do other Blender stuff as well (been at it since 2012) and share my knowledge as much as I can on YouTube at:


  1. Great information, but maybe you could deactivate the wireframe overlay when working with materials. Would be much easier to see what you're doing ;)

      Thanks :). Good suggestion. Since it was just an "already made" model by Saul Cruzz I did not think about it, but of course... you are right :).

  2. This is a great technique, but I wish it was possible to separate concave and convex. Convex edges would show wear, while concave parts would gather dirt. Still a good techinique though.

      Thanks :) I have answered that question in one of the comments below the video. To separate concave and convex it's still "Pointiness" that makes it. Pointiness works with both negative and positive degrees, so you can use it to distinct if it's a "low", "high" or angle that goes in the opposite direction. The disadvantage is of course that it demands a rather high poly to work.
