hey guys, well, gotta a fair bit sorted out with 3d modelling, etc (ie. it all works now

One more thing, with the terrain tiles (all zillion of them), when you have download a new DEM and converted it, how do you get terrain tiles for it? do you have to make 'em yourself? or can you get a rough overlay of the area you want (from another site) and modify it? I was playing around with the korea map/terrain, but with so many tiles, I don't know where to start?
thanx
Ben
