In P3Dv4, I'm using the freeware HDEv2.1 package to replace my sky textures and my cumulus textures (I didn't use the other textures for cirrus and stratus...).
I also use an utility named TomatoShade which alter the shader to make the colors way more vibrant and the atmospheric effect more blueish like in my region. I like it so much.
Currently in re-building mode of everything

It is good to hear that HDEv2.1 works in P3D4. Thanks for the tip.
