RM rocks switched to leyawin's grey vcol edit. Includes rocks 1-5, rock groups 1-4, and cave entrance 1. Edited to fix some excessive vertex shading on rock group 1, included the same change for RR.
While fixing the old cliffs (which absolutely tank the CS when you add one to the render window, holy shit they're bad) Nemon and Gnomey said that they were going to be phased out anyway. That made me realise that there was nothing in the WG or VM sets to replace those cliffs (although VM does have grass/snowgrass/snow cliffs, but obviously not straight rock).
