Animated Update Rotation wrong way

[pmolsen]

I have an animation driven by AnimatedUpdate. If the model has a heading of 358 degrees and I do an animatedupdate to change the heading to 2 degrees, the model spins round anticlockwise by 356 degrees instead of rotating clockwise by 4 degrees. How do I change that behaviour please?

I don't know the tool, but the standard rotation rule is +ve angles rotate anticlockwise about the axis of rotation.
Entering +2 tells it to swing from 358 round to 2 anticlockwise !
If you enter a value like -4 OR +362 degrees what happens, does the rotation reverse to clockwise ?
Is there no a way to specify the required swept-angle rather than the absolute-angle

(If you can figure it out from there good luck!)

Have you tried my suggestions for -ve angle values or > +360 etc

[pmolsen]

I did find that I could overcome it by just getting bigger and bigger with the angles. ie. specifying 352 degrees say, then 380 degrees, then 420 degrees etc. It seems to work.

But I actually used a suggestion Aerilius made, which was to get to 359, then do a change to 0 with a duration of 0 so it spun anticlockwise infinitely fast, then carried on with 20 degrees, 80 degrees etc. That also works.

But it is all a fudge. Surely there is some way of forcing the rotation to the desired direction.
