@IPACS,
Is there any chance of also using the 3DStudioMax exchange format called FBX with your scenery converter tool - I suppose it would take some code alterations but since FBX can represent the MAX format, maybe the changes needed wouldn't be too significant. The reason I ask is that many of us users can't afford 3DStudioMax and we just want to make small changes like adding simple airports (one runway, taxiways, a few buildings, a couple static aircraft, etc..) and a freeware 3D modeler called Blender can export/import FBX.
Thanks
Dave
