this has to work on a cube and they can never leave the surface of the cube.
I've been messing around with Mograph cloners (Object mode) and various effectors to arrange the clones from one side of the cube and then have them travel (randomly) to the other side. Also I've tried using Thinking particles (which will most likely work, but my expresso skills aren't as sophisticated as I'd like).
Matrix Object with TP was my first approach because it's light weight and I need a LOT of them cruising around on the surface. the effect should look like vines growing on the cube.
My friend Rob Garrott, said I should try a mixture of the Shader effector and UV selections. In Theory I understand, but I am unable to execute. Any thoughts?
