Blender Tutorial - Create a Smooth Node with Geometry Nodes
At the time of recording this, unfortunately there is no "Smooth Mesh" node yet in Goemetry Nodes.
While working on some geometry, I found myself in a situation where I needed this node.
So I tried to create one, failed, but then succeeded by accident. And now I understand (sort of) how it works. So I wanted to share this with you: How to create your own smooth node.
