camera through frozen particules Z axis, trouble rotation
on Nov 9, 2006 at 4:19:06 am

Hi I set up a buch of trees from a pre-comp that are set randomly in space. I have a camera going through. But when the camera axis Z rotates, the particules do the same! So my trees start to rotate too. Not making visually sense.
Any thoughts?

You can't do anything about it. Particular renders its particles as sprites perpendicular to the camera. The "cards" have no 3D properties whatsoever, only the points move in 3D. If it's a simple move, you can try to counter-animate the trees' rotation in the pre-comp.

smart idea! About an expression that compensates the Z axis of the camera to the Z rotation of the 'sprites'? How hard would that be for a +6 value keyframe to gives a -6 value?
Sounds like a question for Dan...
