3D Clouds

[TokisanGames]

This issue is here to track 3D Cloud options.

3D clouds are only needed for high end hardware. The two existing cloud systems are sufficient for OpenGL & mobile.

• Noise / cloud shader in a fog volume
• https://github.com/clayjohn/godot-volumetric-cloud-demo-v2
• https://github.com/Bonkahe/SunshineClouds2

Personally, I'm mostly interested in the first as it's already built in. If we could have pre-made cloud nodes built into Sky3D, the user could manually add additional ones around their mountain peaks.

Nice feature, I need it.
I would like to know what you think about cloud blending when introducing a new node, will the new clouds be partially blended with the existing volumetric clouds using a global noise map and a local one, which will give a smoother transition, or will we have a separate shader and a separate noise map?
