Hi everyone :-wave!!!!!!!!!!!!I was wondering, after seeing the quality of 3-D programs (3ds max etc.), if it was possible to model an aircraft in sucha program, and then use Makemdl to create an *.mdl file that can be used in flightsim. If so, how would one go about it???

You could use any 3D software, just as long as you can find a DirectX exporter. I got a reasonable exporter for Maya. Makemdl was able to read these Maya generated .x files and create mdl's. The only problem is you really need a community of people using the same tools
