I ran a biharmonic capture and started adjusting the weights with Capture Layer Paint, however when I modify one bone it generates artifacts across the mesh:
And also modifies weights on other bones:
Mesh is around 460k, I scaled everything up by 10 to see if maybe that would help but still seems to be an issue.
When painting weights if you find that brush strokes are affecting undesired areas of your surface, you may get better results by turning off “Orient Brush To Surface”.
