Noob question regarding texture materials

So I've started messing around with unity so I can make personal mod maps for a game (version 2017.4.9f1 required). but I've run into a problem when it comes to getting textures to apply to my objects in my scene. I'm importing a scene, that I imported from thugpro into blender, into unity, and I cant seem to get it to work. The only other thing I can think of that I haven't tried is baking the textures, but I was told i didn't need to do that and could just import the materials. Other than that I've tried exporting as an obj and then using the Use External Materials option but all I got when I tried that is a new folder with a ton of white materials. I'm very new to this so its possible i'm doing it wrong or missing something obvious. Here's a link to the blend file (2.79): and here's a link to the obj and textures: if needed.

I think its also worth mentioning that the unpacked image files unpacked as files without an extension and had to be manually changed to an image file, if that matters at all.
