Hey, relax! I don’t judge. If you want something half-naked on the passenger seat of your truck, that’s perfectly all right for me - whatever floats your boat…
I don’t really know the exporter or that “pmg”(?) file you want to export in. But I realized that there is something weird going on in your screenshot:
Is that some special material creation tool just for the exporter? If so, you might want to check the exporter’s documenation about its usage.
Apart from that I’m not quite an expert on exporting to game engines. But I would assume that Blender Internal materials translate better to .OBJ than Cycles materials do(?) - so, it is Blender Internal, then.
Let me get this straight: You have no experience or knowledge about texturing in Blender? Zero? Well, give me some time to prepare a very basic video tut or something. If anyone else has a decent tut at hand…
Mind you, though, that your model will still not look like mine afterwards, because I added alpha textures to hair and eyelashes that are missing with your downloads.
