Hi folks.

How do I set up an automatic rotation on objects, via expresso?
I figure I have to get the last frames rotation info and then add a rate of rotation, and finally feed that into the next frame, but how do I do it?

Tried using global matrix, vectors, and a range of others, but the best I get is rotation on all axes. Any ideas?

You should be able to do it with Xpresso. If you get rotations in all direction, then perhaps you should use the local rotation values as input and output? Or am I misunderstanding your problem?

thanks, branmelo..
I just figured it out on my own.

I used a setup like this:
GlobalRotation.H > Vector2Reals > Degree > Math:Add > Degree > GlobalRotation.H

Now i'll make a slider to control the rotation.
HUD is great!
