I'm not very good at weight painting, and even though I get rid of the extra white, moving various joints will still cause them to pick up verities from other areas of the mesh.

Probably, it's an error in the way I actually made the mesh itself, but seeing as how my 3D animation class has yet to reach character modeling, I've not learned how to improve on whatever mistake it was I made.

Confusing!

(At least I figured out how to stop making the mesh SPLIT DOWN THE MIDDLE)
