In my past experience I will choose mesh . but in the sky? that`s crazy
so do you have other ideas?



That’s a tough one. Maybe look into raymarching? Ryan Brucks does interesting stuff with it: https://www.youtube.com/channel/UCSfF-j30GgtB_CpURE2v2jA/videos and http://shaderbits.com/work.
If you can afford it, maybe using a technique similar to the fur shells one could work: https://twitter.com/radiatoryang/status/951175701704642560
