RyanTurned the heat back on under the #KineFX motion capture R&D project. Amazingly, despite not having touched it in months, everything still works the way I left it.
When I last left off, the spines were too stiff because the Motiv skeleton only has 2 (3?) spine bones, and our rigs have more.
I managed to splice a splineIK in upstream of the Full Body IK node, so the skeletons have the same joint count in the spines...
...but the CurveSolver node is giving me unpredictable twist. Damn.
Houdini HangoutCome join @tokyomegaplex and I tonight at 8pm ET as we chat about his process and break down his most recent project. Should be really fun. Hope to see you there!

While talking with Brad at Rigging Dojo about going from #MotionBuilder to #KineFX we discovered that the example file I used to set up my solve network is publicly available.

I've got my #KineFX workflows figured out at this point. The outstanding question is whether I want to leave them as "templates" or make an HDA out of them. Since it's going to be a fully automated system it's probably a non-issue.
One thing I haven't wrapped my head around with retargeting motion capture with #Houdini #KineFX is how to handle scale differences between the source and target. The Rig Match Pose SOP scales the source and/or target skeleton. My method of removing that scale after the Full Body IK SOP is causing foot sliding...
