Improve the quality of thick clouds seen FROM BELOW

[Kappa-131st]

When there is a very important layer of cloud with only a few openings that let the light through... The rendering is quite strange seen from below.

Ex: Screenshot below

On those screenshot, if we look quickly, we have the illusion of having a clear blue sky with a few white clouds (this illusion is considerably reinforced if the quality of the shadows on the ground is reduced)...

Then we actually realize that what we took for a blue sky is actually the underside of 'a thick layer of clouds, and what we thought was a white cloud is actually the opening to the sky.

I think this illusion of inversion between the sky and the clouds is due to the fact that there is almost no texture on the underside of the clouds when they are in the dark, giving us the impression that there it's a blue sky. I don't think it would take much to break this illusion (A different management of shaders or occlusion, better textures, a less dense "blue fog", more contrast, that the underside of the clouds appears to us more "white" to look less like a blue sky... The solutions are not lacking!

Currently, thick clouds are very beautiful and detailed from above, but not great with not much detail from below.

Example : 

Contrast and small details remove any ambiguity
