Yes, sorry it’s not very exciting, but it really depends on what your targets are. I’m assuming that’s focused on the gameplay, so there’s no need to re-invent the wheel in other areas, especially where it’s already been done really well…
As an aside, I do know that the process is basically to do with applying noise textures and / or photos of cloud textures to a large sphere. So, no actual cloud objects in the sky ( they would have to be way too big to be practical ).
