The triangle mesh is thinned according to the vertical error created by removal of a node. So if these hills are not very high/steep and are embedded in large chunks of identical terrain (woods, grassland, etc.), most probably this is what you see. I've got vast improvements in 'level of detail' just by increasing the accuracy of the land use data that goes into terragear. The maximum vertical error allowed is a parameter during scenery creation (TerraGear), so feel free to even set it to a lower limit. Everything else is comparing apples and oranges, though I'd be interested is a comparison of the number of triangles. > >>Will do.

I'll be curious to see the difference! :-) Eventually it all boils down to creating textured triangles. For small areas doing this "by hand" using photorealistic, location specific textures might be feasible, worldwide it is definitely not (mostly because of texture file size, I remember a 12 DVD set of sat/aerial imagery for Germany alone).
