Ok, here's what I'm trying to do. Seems simple but it's not. Who gets a gold star for helping me figure this out.
I'm tring to make the particle move around z-space in a spiral shape (imagine a butterfly flying around a flower).
I have a particle with a light-based emitter, and a spiral mask shape that I created in Illustrator. I can paste that mask shape as positional keyframes on the emitter, put that only gets the particle to travel in X and Y, not Z.
I know that masks are always 2D, but is there a way to make the Z property take its value from the Y? I've tried pasting the keyframes into a 3D Null, then parenting the light's position properties, but that didn't work. Any other suggestions?
Your setup does seem strange. There was a tutorial somewhere on animating a camera to a path, he goes pretty quick, and its not 100% exactly what your doing, but he DOES get an object to follow a path, and in reality that object could be anything, from a layer to a light.
nooooow where did they put that bloody thing
