Hi folks,I am interested in making a very basic piece of scenery for FS9 - basically a small hill. It cannot be a normal mesh because it has to exist inside of an airport (with all it's excludes etc) in between two runways. Currently I have added a 'hill' by making two flatten statements in the scenery.cfg which cause the mesh to bleed through in the middle of the airport but this is an inelegant solution which sometimes gives g3d.dll crashes (I suspect it's the hill anyway)...I have seen sceneries where there are 3D polygons for snowdrifts etc and think this is the kind of thing I need to make - a lump in the airport which has a texture (seasonal would be even better but not essential). Can somebody tell me an idea of where to start and what tutorials I need to read - I think, from a bit of reading, that I need to do this in GMax. Cheers,Geoff

Hello Geoff,There is a default object that may suit your purpose:Any object placement tool will let you use it; I believe that this object is in the Generic bgl.If you want something more particular, then you shall have to design it yourself.Good luck with your project. Best regards.Luis

Airport Design Editor can be used to create hills and depressions on an airport since it allows you to assign different elevations to each vertex in a flatten polygon. This works as long as there are no runways, taxiways or aprons in these flatten areas.

Thanks, that's very interesting - I was not aware that ADE could do this... Presumeably the result is not different to just defining a flatten polygon in the scenery.cfg or can the hills/depressions in ADE be textured?[EDIT] Unfortunately, adding / modifying the airport terrain is only possible for FSX and this hill is for FS9...

Hello:For some links to info on using sloped flattens, see:http://www.fsdeveloper.com/forum/showthrea...=sloped+flattenFor a treatise on use of this function ("Tilted Planes" as LWM3 "Sloped" Flattens) in SBuilder for FS9 see:http://www.ptsim.com/forum/viewtopic.php?f...7d0840a80b1af80In SBuilder for FS9, look at the built-in Help and search for "Flatten"; there is a section under "LWM tilted polygons" that explains this method.NOTE: In FS9, flattens are dependent on the terrain quad tile size for precision, and due to the LWM BGL LOD quad tile matrix structure, vertices for a flatten will fall off to the nearest LOD level set for the terrain mesh.FYI: That FS LOD-11 display-ability is determined by both the terrain mesh slider and a TERRAIN_MAX_VERTEX_LEVEL=19 setting in FS9.Cfg.FS9 max LOD for terrain mesh resolution is LOD-11, and IIUC, flattens may not be displayable if their vertices are smaller than a distance of 19.1 Meters (62.66385 Feet) between the elevation data points of the hill you're trying to build.So if your hill between the runways is smaller than that, you may need to work with a 3-D modeled object; and if you needed to travel over it in FS without "falling through", you'd need to do some tweaks to "harden" its surface.Hope this helps ! :( GaryGB

Thanks for the info - I'll see what I can build...Geoff

There are plugins for GSU that tessellate terrain that could I suspect be used as the basis for creating an mdl.scott s..
