The terrain mesh is sampled at 7. However, see the README for a discussion on the relative accuracy of the source data. These scenery files were generated from preliminary SRTM (Shuttle Radar Topography Mission) data downloaded from edcsgs. The complete scenery set is about 8. FS2004/FS2002/FS2000 70m Global Terrain Mesh for The Whole World.

There are 3 possibilities. Your screen shots depict a relatively flat area and so, they really don't look much different. The area isn't flat and there really is an installation problem.

You are expecting mesh to do something it doesn't. Finer mesh has nothing to do with clarity. What it does is depict differences in ground elevation more realistically. In other words, mountains aren't as rounded off or averaged out.

Try flying over the Alps or some other mountain range and note the difference. If there is none, then you have an installation problem. Since I am not familiar with the addon you are using, I can't be sure how it installs, but check you scenery addons and make sure it appears as active. Otherwise, you may have to use the 'add area' option and restart FS. ProXius wrote: Thanks, It's correct, because when I fly over the alps, the mountains look very nice. But what could I improve then to get the textures more detailed? Because I still think the textures are blurry.

When I put the 'zoom' to 0.33 it looks much better, but flying isn't that great. What do you use? Abd are there some freeware texture upgrades? (are there for example 3D trees?) We are making progress. At least we know the mesh is properly installed.

Since I use Flight1's Ground Environment 2006 (payware) I haven't looked recently at freeware texture addons. Maybe someone here can provide you with a few links. One suggestion. When trying new textures, back up the old ones in case you don't like the new ones.
