“Leaf Roll Joints” vs. “Roll Joints”

I’m not an expert on HumanIK or Mocap, so I’m not going to pretend that I am.

This is what I know…

“Leaf Roll Joints” when twisted don’t rotate the joints below them in the chain. For example when a forearm twist joint is defined as a “Leaf Roll Joint” it will not rotate the hand when twisted.

On the other hand, when a forearm twist joint is defined as a “Roll Joint” it will rotate the hand when twisted.

Unfortunately, I don’t know the consequences of using one vs. the other when doing motion capture retargeting.

When using my LayLo3D Pose Library you will get better results using “Roll Joints” otherwise the forearm won’t swing when the shoulder twist joint is twisted, etc.

When using Genesis 3 for Maya or Genesis 8 for Maya use the “MotionBuilder Compatible HumanIK” configuration to have the twist joints defined as “Roll Joints.”

“Leaf Roll Joints” can also be re-defined as roll joints using the tool included with this plug-in found in the “Tools” menu. You will also get a notification if you apply a pose preset to a HumanIK controlled character that has “Leaf Roll Joints” defined in its definition and an option to re-define them as “Roll Joints” before applying the pose.
