Maybe I missed something here. I have created mesh for my local airport near pattaya. When I loaded it into fs2002 everything seem ok. But when I try in to FS9 I cannot see any change in my scenery.Do I have to do something "extra" for install mesh into FS9? I use LOD12 for my mesh.

Did you set TERRAIN_MAX_VERTEX_LEVEL to 20 or 21 in the TERRAIN section of fs9.cfg?Steve

I've already test with number 20 and 21 nothing happen. Picture can explain diffrence between 2 FS version.Here is how I install my mesh. Create directory name VTBTmesh then create directory scenery inside it. Then put my mesh scenery in to scenery directory.I use menu in FS to install my scenery.
