Title: Smoke Column Lighting Study
Post by: WAS on January 09, 2021, 11:17:42 PM
As the name implies. Always have trouble with lighting tight smokey dark clouds so I did some experimenting. I found the internal lighting model was not good with dark cloud colour, so lowering sun glow power and increasing direct light modular above 1 seems to do the trick.

I can imagine scenes which this could be a volcanic plume in the distance. Thanks for sharing Jordan!

Thanks WAS, I had some fun with it by duplicating the column and having it intersect with an yellow/orange version of itself, as if it's burning fuel.

Oh that's a great idea! I tried a light source at the bottom but had to have to it so bright it was speckling the atmosphere. That's genius. Going to have to try.

You can also use a direct light input for different colrs within the same column. I did that for a black smoke and steam mix.

Might not work too well with this because the direct light modulator is allowing you to get any light at all for a direct light due to it's darkness. It's scalar is at 10 from 1.  The enviro light has a orange tinge for some pollution effect. I'd imagine you could mask the final density altitude limits, and use the same mask inverted on a copied cloud setup with a much lighter cloud colour. Warp the stretched Y mask by the cloud warper and it would probably mix together well enough if the masking is in final space.
