Textures not showing.

Hello

I've just purchased and downloaded Torque X 2.0. Got it all installed ok and have created a new project. The first thing I thought I'd do is put a sun into the level. I've done everything that's in th FPSDemo but I just get a large white rectangle (and a coloured smaller one behind).

Weird thing is, in debug mode if I press F1 to bring up the profiler screen the sun's rendered correctly. It the goes back to a white rectangle when I remove the profiler screen. I can get it to remain rendering correctly by pressing forward, F2 and F1 - after a bit of luck it looks ok.

In release mode it's always wrong and I can't get the profiler screen on to sort it.

Any ideas? I'm presuming it's some kind of renderstate that's not set.
