   how to create .x files?
  If I understood correctly, the only way to directly load meshes into directx application is with .x files. What program may be used to create these files, or, how to convert files of 3DSMax or other graphic programs to .x format?   
  Many of the 3D modeling packages have .X exporters that were written for them. If you have access to Maya, there's an exporter for it that's in the <DirectXSDKInstallFolder>\Utilities\Plugins folder. If you want an exporter for other modeling software, you'll have to do some searching around on the net.   ;  This isn't really anything to do with the API to be honest - .X is natively supported, but its far from the only format you could choose to use [smile]As has been suggested, it is more down to your individual modelling tools. You'll need to find a compatable exporter/converter. Many of the free tools (e.g. Blender and Wings3D) include in-the-box .X exporters and the DXSDK includes plugins for the professional level modelling tools.Any questions regarding those modelling tools should really be directed to the 'Visual Arts' forum.hthJack
