So I recorded a quick tutorial showing how to create a no flip shoulder. It was mainly for the SCAD rigging union, but I'm gonna post it here too, because why not.

Blue Sky Studios developed a tool called a UVN deformer for the Peanuts Movie. Essentially it allowed blenshapes to be interpolated in a UVN space defined by a nurbs surface instead of linearly in Cartesian space. I've used nurbs surfaces to drive other deformers before, but this is the result that all of those technique were approximating. To actually write a deformer for maya you have to use the Maya API (which I am in the process of learning), but since I can't do that yet

So over the weekend I built this baby rig. A majority of the rig was straightforward but the area where his hip meets his diaper presented some challenges. Ordinarily I would do an out, forward, and back corrective blend shape and then use a spherical pose reader to drive them, but I thought I would try doing something new, using a the soft mode deformer. So a soft mod deformer has a center, a falloff radius, a falloff graph, a transform matrix, and paint-able weights. A tran
