Transfer vertex groups weights from a mesh to a Grease Pencil object.

Blender lacks a simple way to transfer weights from a mesh to Grease Pencil strokes.This extension takes care of that.

You can paint over a rigged mesh in its rest position and with one click the drawing can follow the mesh animation.

There is also a special "Each Frame" option that can evaluate the weights of the source mesh in every keyframe, and skin the Grease Pencil strokes accordingly. This can be used to draw on top of an animated mesh and automatically skin the strokes later.
