Please can someone knew any trick or another issus to do a volumetric fog, need this in the purpose for my studies

I have not had a chance to try this out for myself yet, but have a look through this thread by Dokipen:

He is getting some pretty good results with volumetric fog & clouds. Hope that helps!

It really help, as i can see the only way to do it is trought a particle system, i’ll try this out hoping to get the result i’m expecting
Thanks very much
