[1.7]Custom model not getting texture applied properly, various shades of grey

[UntouchedWagons]

I found a person who could make textures for my custom models since art's not my forte. He sent me a texture yesterday and I can't seem to get the texture to work right. As I move my character around the model, the applied colour changes between various shades of grey: http://gfycat.com/TimelyImmaculateAegeancat

SubStationRender class

 

Is this a mistake I made when exporting the model? Is it a mistake in the rendering code or perhaps the texture file? I originally made this in CraftStudio, then exported it as an obj so the texture guy could work on it.

Anyone?

The bindTexture(texture) has to be inside the glPushMatrix()-call.

This tutorial though says it has to be outside. I'll try what you said though.

 

[Edit]

 

Still the same.
