[MDL ED] My ******* Blender model. How do I export it?!?

[The chaser]

Not sure if it's been said before, but you need to unwrap your model to make the UV Coordinates. Click U then click Unwrap. Just unwrap.

[EDIT: Object is the mode I think.]

He has his models unwrapped. If he didn't have them unwrapped, the editor would crash (or simlpy, the textures wouldn't appear). As the textures appear, it isn't a problem with the unwrap.

And it's Edit Mode.
