Hey,
We’re working on a game where player can create creature with clay and these creatures can automatically move. Combining different plugins we made this:

The hardest part is the auto-skinning or auto weighting bones. The idea is to make rig in unity with constrains and applied the rig deformation on the mesh with auto weighting bones in runtime.
For the skinning we’re currently using this : https://winterdust.itch.io/meshskinner
It works fine, there is sometimes weird behavior. I don’t want something perfect, that would be impossible, but the plugin failed in some easy case.
Our goal would be somthing like Blender auto weighting : https://www.youtube.com/watch?v=7piAUK9AQs4
It works with many cases and the result is pretty good.
Do you have any resources to reproduce the Blender’s Auto Weighting in Unity?
I found the source code of blender, maybe there is a way to use it in unity: https://github.com/blender/blender/blob/main/source/blender/editors/armature/meshlaplacian.cc#L634
Thanks for helping!
