I just wanted to do some ground fog, but then I added in a few mountains and two cloud layers on top.
While the cloud texture looks promising I think the distribution does not yet.
Clouds close to the horizon should show distinct horizontal layering like the ground fog does.
Maybe the volume boxes can be scaled down vertically?

The clouds with sun light shining through in the Denoised and Composting image (Thu Oct 25, 2018 9:54 pm) look great!

Looking forward to the follow-up. :)

@epilectrolytics
I agree. Also it would be great if the whole system was reusable and generic.

Since the heating in my flat is currently broken and it's getting kinda cold, I rendered this to heat up my room a bit:

Atmosphere looks great!
Do you intend to go for the full environmental & atmospheric synthesis (inc. Rayleigh scattering)?

Thanks & keep it up!

I'll use the pre-computed model in LuxCore's sky light.
I don't like long render times and I'm more interested in creating clouds.

Rotated sun to the right + a few minutes in Photoshop.

front looks ok, like cumulus or fog type of clouds. But background clouds look very wrong.
If the horizon is somewhere on top of front clouds the ones in bg should show some perspective and atmospheric distance. Especially since you show mountains which have structure that should be high enough above cumulus that you also demonstrate in foreground of the image.

Keep in mind I only render these to keep my room from freezing ;)
I only change a few parameters, do a few viewport test renders in a couple of minutes, then I let it render.
I rearranged the cloud layers, but I'm not sure it helped.

Finally, here's the scene, if someone wants to play around with it.

Requires at least v2.1beta1 (older versions lack the Remap node).

Also, just a different camera angle, no post and no denoising this time:

Here's something for procedural cloud creation > Procedural Cloudscape Generation in Cycles (now Eevee!)

Should it work with Lux?
I haven't tried it yet...
