Removing flatten default airport FS9

A crazy thought: Is the flatten a part of the 38m mesh?To check if it is, use the original FL file, check the height, then draw a new polygon with the same height, half the rwy lenght and export it, then minimize SBuilder and rename the file to the correct default FLxx name. Maximize Sbuilder and from where the new polygon stops, draw the rest of the rwy lenght. Then delete your first polygon plus the rest of the flattens in the file, so that you only have the freshly drawn poly. Now...click each point, check properties, and input a slightly decreasing height value for each point along the rwy. Leave the first two points that meets with your first poly (which exists in the already exported FL file) the same height as the original flatten. Now export your new "sloped" polygon...it will be named your project name plus "LWM3". Put this in the same folder as the other FL. I don`t know if it will show up this way, but it will certainly show up if you make a separate "myairportscenerymyLWM3" and add it to the scenery library with a higher priority than the default. I have "refined" ugly flattens this way in order to integrate them better with the scenery around the airport.Bottom line, flatten a part of the mesh or not...one can always place the new flatten files in a separate scenery folder like described above, leaving the original flatten like umm...original :-)Cheers,A.Thomsen
