This is what I got when I used plain bone heat.
Bone heat also causes this guy to scream when his head and neck are tilted back.
Good reference. I kind of went with the second option in the first picture, and I’m not sure what I could have done to mess it up. Then again, all the models on that page have their arms in a sort of T-pose while my model’s arms are pointed down. A lot of the models on that page also have triangles, which makes things confusing since I’m trying to model entirely with quads (except for the tips of the teeth, horns, and claws).
