Cloud creation advice

Hey guys,

I am trying to make extremely large clouds so that a city can poke through them but I can seem find any tutorial that will help me. I have tried almost all of them from raymarching type clouds to using Houdini and what not. Though the clouds Ive been making look okay they resemble fog more than anything. I’m trying to achieve something along the lines of this.

I was hoping someone would know of way to maybe cheat this as it doesn’t need to be animated clouds and the player wont enter or move through the clouds. Any suggestions would be appreciated. THANKS!!!

Anyone know how to make these clouds?
