Nice. I was just toying with those problems myself. Painting in the Terrain room was very slow and the feedback wasn't great. I've painted height maps in PhotoShop before and am okay with doing that. My thought has always been to create roads and paths by judicious painting of an existing generated terrain map. Also tried opening in VM, but even after several decimation steps the terrain was too large to work with. I'll have to explore convert options more closely. Actually, truth told, I just spend a frustrating evening working on landscapes in Carrara, when every few minutes I'd accidentally slide a slider too far to the right -- and have to force-quit Carrara as it went into hour-long calculations of erosion filter or some-such. Looking forward to 6 to see how that runs!
