Hi,in a FS2002 addon scenery I use in FS 2004 (Flylogic scenery LSZH Zurich/Switzerland), the grass textures of the default scenery are blurring through the apron textures of the addon scenery at certain view angles, combined with a kind of flickering on and off.I guess this can be cured by an exclude or flatten file, but I'm not sure and I don't know how to do it. I tried several tools (e.g. ExcludeBuilder, FS Scenery Creator) but I got none of them to work as they are supposed to.Would be great if someone could help me.Thanks in advance.

Sounds similar to several SimFlyer locations. They are working on it, and have been for some time seeking a solution. If I am not mistaken, after installing new mesh and landclass I am seeing the same thing at some default airports.At all except one of the SimFlyer airports, a quick temporary fix has been to either check, or uncheck "ground scenery casts shadows" in your display settings. When taxiing and the scenery starts flickering back and forth doing this clears it up until after you takeoff. When you land at another or back at the same location you have to do the same thing over again. Dosn't seem to make any difference whether it is checked or unchecked, just reverse the action and the bleed through ceases temporarily. You might try this and see if it helps at all at your location. I realize this is not a fix, but just a bandaid.Hope it helps a little bit at leastRTH

The grass polygon is at a different elevation from the elevation of the ground. Use the Cessna 172, setting on the ground, go to slew mode (Y) and read the elevation at the top of the screen. Take that and subtract 3 feet or 1 meter from it. that will give the true elevation.Joe W.
