I modified a default human mesh in blender and exported it as a proxy.
I just modified a small part of the original mesh, and it now has more vertices (i.e added a penis into the body mesh).
The penis works, but some different positions, I didn't even touch, don't look good anymore.
I added the default vertex groups, and added two new vertex groups for the penis, (penis, balls) and removed them from the other groups (mid, left, right).
I think, I have to set the vertex groups correctly, but I don't have an Idea, how/where. Can you help?
