Does anyone know how the shelf tools do their eye rigging? I'm looking at the simple biped network and I don't see anything in the lookat parameter of the eyes, and the lookat nodes are in a separate branch from the eye geometry.
Any help is much appreciated!
Edit: Looking inside the pretransform nodes, I can tell those are being rotated when I move the lookat object. The transforms aren't changing though, and I don't see any expressions or chops references.
