I can try,
I need a bit more info. What type of mesh is it, is the texture present and referenced in the file.
You can test this, if you load the model file into wordpad (even a binary file, BUT DO NOT SAVE IT AGAIN!!!) and do a search for the texture name in amongst all the junk of ascii chars displayed. If the name is not found then your model has no texture reference.
Ted will load any texture as long as its referenced in the model and is bmp,png,tga,jpg.
