How to find textures for .psk model?

[spiritovod]

It's not quite clear what you're trying to do. When you export a model to psk and it has linked materials, all materials would be exported as props txt files along with all textures, used in those materials. You can open those txt files and take a look at textures used there (with paths to them) - alternatively, you can do the same in the viewer by pressing "M" when a mesh is open, and then clicking on respective materials names. Reverse operations are not possible, like finding model by knowing only texture used by it.

@Adon1111222: It also depends on engine used by the game. Aside from props there are mat files exported for materials with filenames of used textures only (which can be opened in any text editor as well), they're used for ActorX importer. Exported materials and textures are stored according to original file structure, but almost all games are placing them into different folders from meshes themselves - usually it looks like Char_Folder/Materials+Mesh+Textures subfolders.

If you don't want to search through all exported files, you can do two things:
1) Open mesh in the viewer and like it was already said above, switch to materials mode with "M", then click on material name -> click on texture name -> see internal full path to it.
2) Switch to flat view in umodel, find mesh by its name, click on it once (without opening it), then switch to normal view and look at current directory structure (file tree will expand to the folder with the mesh). You may see near folders where materials and textures may reside.

In case of some complex materials and particular games you may expect no actual textures at all for some materials, in that case only materials properties would be available.
