.Map :: MoHAA Mapping

Here's my friends problem, He reading the tutorial to learn how to make a room, so he follow all the steps up the hollow it, so he does, next he loads the textures, with his brushes selected then choose a texture, but the walls don't change at all, they stay the same way, no texture at all anywhere, any ideas? This has never happen to me

Go to View---->Render Quality and click Nearest.

The textures should then show up in the 3D view.

Did he accidentally hit the spacebar and now has duplicate planes ? I'd just redo it .

when he makes a wall for ex. it is just the out line of it dose not see the blue and black squars.

The only time I have seen that is if I have a brush selected and hit reload in the texture menu . With nothing in the texture window all I see is an outline .
