I have just downloaded particleIllusion for After Effects and it is ok but for some reason I can not find the Record position. In particleIllusion 3, when I put a particle in I can right click and just record position to move it with the video. I can not find that in particleIllusion for After Effects. Can someone please tell me if there is something like that in particleIllusion for After Effects and if there is please tell me how to do it.
There's an After Effects function for that... called "Motion Sketch". Use that to draw your path, then link the emitter position parameters to that. I'm sure if you Google "After Effects Motion Sketch" you'll find tutorials.
