it should work, Dan. Although if you're doing it in jscript there are some
problems with re-assigning the arrays at the end of the loop. I used a
cloud-based script and just looped through the particles, setting the
rotations as I needed them. Worked pretty well for faking patch deforms and
still getting the orientation right.

Subject: Particle rotation event script....
I have a particle cloud with a bunch of instanced characters and their
rotation is set to 'align on velocity' but I would only like this to affect
Y rotation. I thought I might be able to take in the rotationarray for the
cloud and set the x and z rotation back to 0 on every frame but it seems the
align on velocity is applied after the script event, thus cancelling it out.
So the question is... how can I reset these or how can I derive my own Y
rotation from the velocity? I'm not much of a maths head ( I was once,
honest! ) so any help would be greatly appreciated.
