heyas; yep, check the 'sky dome height' stuff for the colour map. and/or change the colour map gradient colours. and the fog/haze settings. you might want to put some cloud planes down under the horizon, once you see some blue down there. or, you could point your camera up and stick your object up in the air. or, heck, turn the camera upside down (make sure you turn off 'keep camera level' with that one).
