Hi all Say I have two quaternions q1 and q2, q1 == previous orientation and q2 == new orientation. How would I constrain q2 so that the difference in angle between q1 and q2 does not exceed a Max rotation constant? Thanks

The angle of a quaternion is given by 2cos-1(a), so you can redefine a as your maximum angle, and then normalize by adjusting the other components.
