For a project I need a solid quadruped setup, for which the 3jnt seems to be the logical hind leg solution. I already notice some issues mentioned on this forum. I also have one.
It is important to me (and the future animators) to not have any form of squash and stretch. If I turn this of (by setting stretch to 1) I still experience local stretch when one of these controllers are translated:
The ankle even produces very weird non-uniform scaling on the bones (shearing?).
I use the rotational plane method because the spring-option gives a faulty bone-chain which does not follow the guide. Both methods generate the stretch/shear.
Is this a bug or am I using it the wrong way?
