Following the backflip, I decided to add a Forward Roll on the ground.
The Dilemma: When pushing for these extreme dynamic motions, I hit some "mesh clipping." In film, we hide this with camera angles, but in games, you can't always hide.
Question for Game Animators: Do you "break" the rig/scaling to get the pose, or do you prefer adding extra helper bones to fix the skinning for these extremes?
