Just a quick share of me exploring APEX today… a graph with joints deforming joints.
There's a Base skel and shape (red) and another face skel and shape (blue). Base skel deforms base shape and face skel. The bone captures from face shape are copied to Base shape and are then deformed by face skel.
I'm sure there's a proper way to do something like this — yet I'm proud to even get a result
I'll prepare and upload a hip later, gotta catch that office xmas party.
