I am trying to get a decent foot and ankle retarget using the ikinema for motionbuilder plugin. I have a blade skeleton as an input and I am retargeting that solved blade skeleton data to a character rig. I notice that with a variety of settings that I have attempted, that the feet keep coming out squishy. I can clearly see the blade foot bone staying firmly planted, but the ikinema retarget keeps straying more than I would like.
My question is, has anyone had success firmly locking the feet down? I particularly notice the squashiness when arms are overhead or during lunges with the ROM I am using for tunign purposes. I suspect its some kind of gloabl optimization happening, but is there not a setting to prioritize the feet and ankles more heavily?
