Various models listed on this site have differing file extensions and quantities of files. From what i've gathered, the .x files are the real meat of the models, while the .bin are the textures. I ask because those models that have worked for me have contained 3 .x files and 3 .bin files. However, any other combination of .x and .bin files doesn't seem to create a model, and when previewed in rebed i get a critical error message in French. The question behind the question is, if i download a model with only one x file, (or any other combination of the above mentioned files) what do i do to import it?
