I already asked about the Ipod Nano tutorial and how my light could follow my own path. I received answers which helped me a lot. Thanks to all of you.
I have an other problem: I created several paths (or expressions) with different lights to make my composition more full (different strokes follow different paths, overtaken each other). My problem is: I want that each path is in different color (gradient). What I did is I duplicated my solid with particle and my light.
I can change my Particle's color but I can't manage to make each other independent with just one light. For example:
I would like to have my Particle 1 (blue to white) controlled by my light 1 and Particle 2 (red to green) controlled by my light 2.
But at the moment I have:
Particle 1 on Light 1 and 2: blue to white
Particle 2 on Light 1 and 2: red to green
Does someone have a solution?
If my explanations are too blur, I can send you a basic after effect file.
Do not hesitate to contact me, thank you in advance.
Give your lights unique names. Particular looks for a special string which you can define in the "Options". So name your lights Streak_a, Streak_b and so on and give each of the Particular instances the proper assignment.
