I've wanted this for years. There's more, too. For instance, farmland looks different in different countries -- when we went to the more photorealistic textures a couple of years ago, we dumped a texture that I think Erik Hofman had created for farmland that, on one hand, looked less like a photo and more like art, but on the other hand, looked *much* more like farmland as you would see it in England and parts of northern Europe. And I remember Paul Surgeon creating one that looked *exactly* like farmland in places like Indiana/Illinois/Iowa, but not like in the western U.S. and definitely not outside the U.S. Middle Eastern/central Asian cities look different than western ones. And there ought to be different parts of cities -- the types of buildings you see in the inner city (and their frequency) should be different from the types you see in suburbs, and both sets should be different in different places around the world.

I guess some of these issues could be improved that way; but lines of constant latitude or longitude aren't really correct, even for the ones they would improve. The region boundaries won't look realistic. The right way to do it is to use GIS data in TerraGear, and to expand the groundcover types coming out of TerraGear. Once upon a time, it was actually in the works to start creating those groundcover types/material definitions, in advance of actually labelling ground polys with them in TerraGear, so that people could experiment with setting them in fgsd; but I was gone for a while and I don't know what the status of any of that is now. -c -- Chris Metzler [EMAIL PROTECTED] (remove "snip-me." to email) "As a child I understood how to give; I have forgotten this grace since I have become civilized." - Chief Luther Standing Bear
