I was wondering if there is a way (tool) to isolate which textures go with a specific model/bgl/xml file.

History: I've been enjoying the many freeware, gmax created, objects that I can place around the FS world. Some developers provide the xxx.gmax file with textures. I figured out how to install gmax and open the xxx.gmax file which tells me what textures are needed (add them in) and then do an export which gives me the mdl and xml. With this I can easily place the object with the xml and create the bgl. Voila! (proud of myself)

part 2: Some developers share the already created model/xml/bgl and textures. Usually in a bundle of many objects, thus a single texture folder that covers every mdl.
If I want to use only one of these models and its associated texture(s) ... How can I discover and isolate only those needed textures other than trial and error?

Thanks for any help or suggestion.
