Whenever I export my models as a .x file, I load it up in the DirectX viewer to make sure it exported properly. Well, I've noticed a trend that the DirectX viewer can only load the model correctly if there are no textures associated with any of the materials. Is this a problem with the Blender .x exporter or is there something special I need to do to make sure everything gets exported properly? Thanks.

based on my personal experiences with blender, I wouldn't try to export anything but .Obj meshes. Even when the scripts are updated it still doesnt work like it should. I've hear all the time about people having problems trying to export .X files from blender. I'd suggest XSI for .X models or animations. If not that then Milkshape. I know it was created as a mod tool, but you'll probably have better luck with that than blender. Just my 2 cents.

Its cuz that exporter is jank. If you PM me, I have an exporter still I believe that will work correctly. Otherwise just google blender .x exporter.
