I guess this is a part of dark shader but i've noticed a problem i can't seem to get rid of - when using the flag for it to produce a temporary camera, a square the size of the cube map is put top left of the screen during execution, slightly darkening everything underneath it, it's very bizarre, when i try using a different camera it draws the entire cam's view to the screen, or leaves a completely black screen, depending on wether i used sync mask or sync camera

I've tried setting up a camera and skybox to a point way out of the field of view but still the same problem - it's hard to produce the code i have cause it's fairly tangled up with each other but wondered if anyone else had had a similar problem
