I've been studying some of the recent tips on clouds and rocks with pretty good results however I keep running into the same problem, my rocks have a yellow tinge and my clouds have a blue hue. This is under normal daylight conditions. The rocks are textured only in levels of gray (maybe a bit slight hint of blues here and there) but always render out with a yellow tinge, not gray at all. The clouds seem only to be an issue with high density, low edge sharpness as recommended to make good cumulus, (works a treat apart from the blue hue). Any ideas?
