| This is the same "trick" as the Gas Giant shader and its a bit buggy for very obvious reasons. I like how it looks and I was asked to post it.
This only works with v .96 and will probably be pointless after the next version is released.
- Edit: Will leave comparisons as they are roughly the same -

Results on your PC may vary.
-Edit: Updated shader thanks to Space Engineer
Install instructions:
For the new shader folder download the shader files from Space Engineer's post here http://en.spaceengine.org/forum/17-1200-14299-16-1351938131
For my own edit download the shader file in this post http://en.spaceengine.org/forum/17-1200-14300-16-1351939888
Go to data/shaders and backup the original
Drop the new tg_clouds_height/color files in there
Enjoy

Once again this may look messed up, report any issues here and I will tell you what variables to tweak to fix them.

| Nice! but:
1. All planets will become gray like in the other mod? xD
2. Does it impacts on performance? xD
The universe is not required to be in perfect harmony with human ambition.

Nah, it's just the ones that are completely cloud covered.
Anyways, while it does break up the hypercanes on tidally locked worlds (i've seen a few where it was absent for some reason or other), it actually gives more variability to them.

If that were the case I wouldn't have even bothered with it.

Possibly, but I haven't noticed any drops in frame rate.

| This looks wonderful!
Looks much more like Earth's clouds and not ~100% white opacity.
I like it.
Alot.

| Quote (DoctorOfSpace) Planets with coverage 1 will look like this
Coverage 1 means that the planet has an opaque cloud layer, and SE uses optimization - the surface and water of such planet is not being generated and rendered while you are above clouds, this saves memory, loading time and framerate.
Quote (Salvo) Does it impacts on performance?
This is a generation shader, it is used only for generation of textures when they appear the first time, not for rendering. So it affects generation time, not performance.

Is that shader controlled and if so what shader(s)?

I don't understand what are you asking.

Does a shader file do this
Quote (SpaceEngineer) the surface and water of such planet is not being generated and rendered while you are above clouds, this saves memory, loading time and framerate.
And if so what shader controls that feature?
Or is it not done through a shader?
Not entirely sure how to word this properly

| Shader doesn't control rendering engine, so no, this is done by CPU code.

| DoctorOfSpace, you completely remove the using GetCloudsColor() function, this is why opaque clouds becomes black and white. And on desert planets, clouds would be only white, not of yellow or red dust color. Alsp, you remove the using of cloudsCoverage parameter - it is impossible to control clouds density by this value now. And, copying the HeightMapClouds() function from tg_clouds_height.glsl is not neccessary, its value is cached in the NormalMap texture's alpha channel (.a or .w component).
So I found a better solution to making clouds more "soft" - mode cloudsCoverage to the tg_clouds_height.glsl shader and remove saturate() function from tg_clouds_color.glsl. Download the new shaders in the attachment, and extract them to the \data\shaders folder.
Screenshots for comparition, before and after:

| Wow man thats fantastic. 
Edit:
Tried it out, it really does look pretty nice.
Might tweak it a bit though
Edit:
Alright thanks for the fixes. With your new shader I was able to do a bit of mixing and matching of my edits and yours.
Your edit is top, my tweak is bottom. This keeps the look from my first post but also your slight edits to fix the Opaque issues. I have attached the shader file to this post.
Bravo sir
Edit:
Did quite a bit more tweaking to the variables to try and get a better look. Removed old edit and attached new better edit and here are some screens.
This shader is the new attached file.
