- A mesh, with a vertex group.
- A bone.
I want the bone to behave as though it were “parented” to the group of vertices.
The “Copy Transform” constraint cause the bone’s location to follow the average position of the vertices. This is good… but … the bone doesn’t copy the rotation of the vertices.
I would expect that its global rotation correspond to the average of the of the vertex normals. This does not happen - I’m guessing that there’s some sort of space switching issue, but I don’t know why- I set the constraint’s “source” and “target” fields to “global”. If I set the constraint to “offset” I get something better- the bone points straight out from the mesh- but the bone still rolls on its y-axis, and if I rotate the mesh into the correct configuration, the bone starts rolling into the mesh.
The Blender WIKI seems to suggest that this kind of constraint is do-able, so is there something I’m doing wrong?
“Child Of” doesn’t work either.
