It’s a lot to watch, but, those thinking about the nuts and bolts of creating rigging for an eventual standard character rig might see some really cool ideas. It’s not really my area of expertise, but, the workflow and methodologies seem superb. If something like the rigging system, constraints and IK actions could be implemented it would (it seems) be a fantastic setup.
Hopefully @leviathan has noticed this link; different skeleton model coordinate systems are a real problem for scripts and he’s working on a solution I think.
yep, been looking into Blender as well
