I uploaded the weapon model thing. Didn't expect it to stay there when I left my browsing session, so I uploaded the quickest thing I could find in .obj on my side.
It was just a high poly version of a model from an N64 game. The normals seem to have been messed up, which might have been an error on my side of exporting.
I assume it didn't load the texture because it wasn't in common picture format, it's suppose to look like this:

No idea what happened with this model. It's suppose to be a house with some rocky areas.

One thing that would be neat would be to use the mousewheel to adjust zoom. If that's possible.
