Anyone figure this out yet? I have a particle system of airplanes that need to bank. I keep trying to fake it with rotation and spin operators, but it's not working very well.

It just seems like it should be so easy! AAAAAAHG!

As you can see from all the quick responses, this is an easy thing :)

Do you have Box3? I have not tried to do this yet, but I think it would be eaiser in Box3 than trying to script. If I get a chance, I may play around with this, but I can't make any promises. Somewhere on the Orbaz site there is a very brief description by Oleg on what it would take to create this. I will see if I can dig that up. If I could see the math behind doing this with a standard Max object (as opposed to figuring it out myself :P ), it would be pretty simple to translate to PFlow.

Allan McKay showed this planes fly-by (and bomb the terrain into oblivion) in one of his tutorials for afterburn i think. If you use "speed by icon" and animate it using a path constraint to follow a spline, you can use "follow" and "bank" to make the icon bank. Then in the speed by icon you can use "Use Icon Orientation" and voila, bob's your uncle. :-)
Hope that helps.

edit: Hmm, i just doublechecked if it works as i thought, but i'm not getting the results i expected neither.

that would be restricting tho, i know a freebie is coming that does rotation banking.

Like charlie said, spend sometime in box 3. After a week you will get comfortable with the workflow and then you will be able to make particles do anything :D

Thanks guys,
I actually had to wrap this up. I managed to fake it pretty convincingly by splitting off particles into different events that had forces that would push them one way or another, and then rotate them accordingly. Then I hand animated a bunch of extra planes to fly right by the camera over the course of the shot. It wasn't perfect, but it sold the shot.
