Is there any way to make a bone rotate so that it is spinning at a high speed? Rotating and inserting rot keyframes every few frames just makes the bone spin back and forward, rather than just going one direction.
Just insert two keyframes and in the IPO editor just use the curve extend options.
Inserting rotation keyframes on a bone results in ‘Quat’ channels being keyed in the IPO editor. What exactly do their values mean?
Yeah set your bone’s rotation mode to Euler XYZ or similar first. (Blender 2.5 only)
That’s the problem. So there’s no way to do it in 2.49?
Sure, it can be done in 2.49, just a bit different and not as easily read by humans. I keyed 4 90 degree rots 10 frames apart, then choose cyclic extend mode for the 2 curves affected. It’s not 100% smooth and constant speed, but changing the curves from beizer to liner should fix that. Speed can be controlled by scaling curves in the ipo windows x-axis.

Maybe “flip quaternions” can help to make the rotation continuous. But that requires fiddling around with it, not sure it works.
Thanks for the tips. I’ll play around with those suggestions and see if they’ll work for the rig.
