I've been trying to get a 'bludgy' look to planets, but I can't seem to do it. When I pipe in some extreme scales, instead of a rocky, "Deimos" or "Phobos" styles asteroid like moons, I get blocky, squared of edges resembling a standard rock object.
Is there a way I can achieve this effect with a planet? I have tried the rock object, but it seems to just crash Terragen after a certain scale at about 1/50 an actual moons scale.
