Oolite Bulletins

I'm working on some ships at the moment now suddenly for no good reason all my shaders are coming out black. The thing is I'm running exactly the same computer specs at work and all is fine and the home compy WAS working fine. So it's not my code and it's not the computer could I have a graphics issue? Suggestions? I really need to be able to see these things in order to finish them off.

OK new information! It's something about the shaders. Only shady ships are falling over and only the parts of them that run through the shader programmes.

Different versions of oolite doesn't help. I'll be trying this on another mac I'm dusting off just to be sure. I think It might have to be an op system reinstall.

Arses.
