i'm working with trapcode Form and i want to have a pre-comp'd layer be the layer map(RGBA) for a single sphere layer of particles. the effect i want is to have scrolling text and or messages that move around the outside of a 3d sphere. this works easily enough except for one thing: there is a seam where the composition wraps at the backside. is there any way in after effects to create a composition which loops or is seamless at the back end? just wondering if there's a good way of doing this so the seam isn't evident.
