I've been going round in circles with this: No matter what I do, I can not see my model in FSX at Sea-Tac (or anywhere else I set in the placement file xml). *Scenery density set to "Dense" in the sim. *I've tried exporting the Oil rig model without modification, but that doesn't appear either. * LOD export tool says" .x file has no GUID or FriendlyName, the Max file does have them however. I've tried exporting to an X file from the File menu, as well as the LOD tool. It is as if the X file exports succesfuly, but without a GUID or FriendlyName. *Another oddity that may be related- ACES Documentation and Aces Tools menus appear twice in 3DS Max! I've checked user paths under customise, and there is only one path that I made manually. * my PC is set to dot for the decimal point, not comma.
