Blender 3.1 Raycast Node - Geometry Nodes - Weight Painting

This runs with Blender 3.x Geometry Nodes.

It works pretty well even on old hardware, because it uses Instances.

You need Blender 3.0.

Video Update 20.01.22: to play along with this file, for example adding a modifier, you have to realize Instances, but then it gets sluggish, because it handles real geo.
