How to paint material where actor moves?
Simply put, I am trying to figure out a way to paint a material/texture wherever an actor steps, like a trail. After a certain amount of time, that texture would revert to whatever it was before the actor moved over it. I haven't the faintest idea how to go about this, any ideas?

The best way I've found to do this is by using a trail of decals. Decals project a material (which can have a texture) onto the ground, so that you don't have to mess with the actual texture of the ground. Keep in mind that decals only project in one direction & need to be close to the surface of projection.
