Subject: Rotation controllers: Euler XYZ vs. TCB Rotation

Hey all,

I have some questions regarding rotation controllers.

I just manually (Set Key) animated a bone from one rotation to another, and the (default) Euler XYZ controller produced an awkward interpolated rotation, as if rotating around an arbitrary axis to get to the destination, instead of a 'direct' rotation.

I then assigned a TCB Rotation controller (which uses quaternions) and the rotation performed as expected.

Now my questions are:

  1. Since it's not the default rotation controller (anymore), what are the drawbacks of a TCB Rotation controller?

  2. How would I use a Euler XYZ controller to get the same 'direct' rotation between 2 arbitrary rotations?

Thanks in advance for any insights!
