So my priority here was cleaning up the geometry and getting all the textures onto one UV map. Not my best high-poly model by a long shot. Part of it is that I'm unhappy with textures I paint myself, and part of it is that I can't get a good UV map of the asteroid that's seamless. Whatever I do to it seems to make it worse, so here it is. If someone wants to take another crack at the Cheops in the future, starting from scratch, they're more than welcome to.
