"Link with orientation " question 2004-05-18 - By key
Back
I've also had problems with multiple link with orientation keys where
points would shoot off in space. Maybe reordering the stack might help
you. Or make sure all "link with orientation" keys are off of one
cluster.
In order to get greater control, I wound up doing shape animation
linked with an expression to the rotation of the bone.... which is what
"link with orientation" is supposed to do in the first place! If you
have a character that is already enveloped you might get some erratic
behavior still. I think it's the way xsi tries to average out the
deformations. Hopefully this is all fixed in 4.0.
