I modified the "Labs Snow Buildup" tool slightly for this but the Labs tool itself should demonstrate to you what I'm seeing.
So the geometry is nested like so:
Parent
---> Child 1
---> Child 2
---> Child 3
---> Child 4
---> Geometry (Transforms here)
Guess I have to duplicate the geometry and bake the transforms for the tool to work.
Thank you.
Cheers!
