Actually, Blender 2.49b has the most exporters built in a program I have seen.
As for the textures being gone, that happens to me a lot. What I do is export to obj, import to Blender, and reasign the materials. Don't worry, even without the mtl the UV's are still inside the obj. And then export again as an obj and save it in a folder. Also, another important bit of advice, in Fragmotion, in the textures section, usually the texture directory is C:/Users/dsdf/desktop/z.png or something like that. This can cause issues in exporting. This is another way of how you can fix it:
1.Put all your files and textures into one folder. No folders within folders, and no folder for the textures. All files placed in one folder.
2.Open the file in Fragmotion.
3.In the textures section change the directory to this: texturename.png (No C:/, no user, no desktop, just the texture name and format.)
4. Do this to all textures and export to the same exact folder everything was in.
5.Now export it to obj and materials should work again.
The second method I gave uses a trick in directories to get the textures wherever the 3d model and texture are in the same folder.
Also, another thing: If the Uv maps seem to be all messed up, look at the textures. I've seen TGA's get flipped a lot when saving and exporting. Just flip the texture in paint and try to assign the materials now.
Tell me if this helped
