Model shaking when not moving the effectors endpoint #6

Closed ptanugra closed 5 years ago

ptanugra commented 5 years ago

Hi Professor,

In IK mode, How can I fix the problem of certain models (particularly beast.json) shaking even when I'm not moving the effector end points? This is fine for other models such as chimpanzee-hands, robot-arm ..

Other than that, I can move the effectors around and the bone parts would follow around correctly

I'd start by debugging your line-search/gradient descent. Print out your energy and make sure it's monotonically decreasing.
