Testing Terragen 3.4 beta. Cloud looks like some spirit of the North to me.
Cool................has said Manitou swallowed a blue light source? :)
There is no light source, the glow is an effect of the cloud settings combined with a yellow colored fractal final density as opposed to the more usual gray. I believe the blue shows up as the complement because of the yellow getting scattered or absorbed or also it may be due to the color being unclamped.
Cooler.......... ;D
cooler colour trick...gonna file that.
You would need those colors in the ice too. Nice effect.
