Hi Aras, I've found this https://docs.google.com/document/d/1e2jkr_-v5iaZRuHdnMrSv978LuJKYZhsIYnrDkNAuvQ/edit and in the “HD Render Loop” section there is info about "Volumetric Lighting" and "Sky/fog atmospheric scattering model.". Does it includes Volumetric Clouds? Thank you and greets!
Various volumetric things (sky, clouds, scattering etc.) are on the roadmap, but not very much near "top" of it, and timelines are uncertain.
