As for automating things - like it was already explained above, it's not really reasonable within umodel (although possible), because most such adjustments would work only for games using particular materials layouts. Doing this with all required checks and possible issues with custom materials will take too much time and knowledge, although there is an attempt by mdro on this matter (see this topic for more info).

Mat and props files were designed for psk export and ActorX importer for 3ds max (available in downloads section), which allows to apply textures from generic materials to the model. People using blender are probably automating things with some python scripts, but that's out of my knowledge.

@gargon: Like it was said, importer works more or less fine only for generic materials - like one unique material per mesh section, with one diffuse and one normal texture. Most materials are more complex than that though, especially PBR materials and materials created for anime style graphics, where a lot of things are done at runtime with shaders.

Mat file only addresses one diffuse texture and one normal texture, collected from material properties as most significant ones, and also other linked textures (which are not applied by default). In the same time, all parsed properties are exported to props file. In this case, as you've noticed by yourself, there is one material applied to all mesh sections, but there is only one mat file with one diffuse texture, because it's one material. In such cases with custom materials the only way is recreating them outside of umodel based on material properties and your own understanding how they can be used, including possible automating the process. Unfortunately I can't help with that.
