Mesh Deform to Weights
Does it work on characters with many bones?
Yes, but conversion time grows with the number of bones.
Does it create new bones?
No. It only uses the bones that already deform the cage.
My objects already have weight paint in some areas. Will I lose it?
Not if you use a Vertex Group on the Mesh Deform: only the group's region is converted, and the rest is left untouched. Without a vertex group, the object's bone weights are replaced.
Does it work with any rig?
It works when the cage is deformed by an Armature modifier with vertex groups. Bone envelopes are not converted.
Do I still need the cage after converting?
No. Converted objects are deformed directly by the bones.
Is the result the same as the Mesh Deform?
Very close over most of the mesh, with a small difference near joints.
