This is the first test done just yesterday. The overall general shape is present, however much more needs to be finished. For example, the anvil is lacking in proper shape, the lower cloud bank needs to look more like convective cumulus, the anvil edges could use some feathery cirrus outflow and thinning as you get near the edges, the thunderhead convection itself looks to straight in some parts, and now what works. The overall shape is present as said, the scale is proper of a thunderhead based on the tallest ones known, about 21,000 meters at there tops, the width of the storm is correct for average storms even though it may not look like it here and there is billowy patterns but they could stand to be more tightened.
Very cool. Must have taken some time to render with that height?
Thank you. It was around four and a half hours to render.
That's pretty much indeed (for me, anyway).
Very nice!
Nice work! Looking forward to seeing how this progresses.
Looks good. Seems like it has a lot of potential.

OUCH! not ideally suited for an animation.
But very impressive work!
Whew, I dunno if it would even render on this old dell. You gonna share when yer done? Would love to try this on the Corsair

I intend to share when there is a satisfactory enough point to consider it. I can not say how soon that will be though. The anvil still does not look right, the billows need to be more tight and sharp and there is still too much break-up.

May I say in the spirit of self interest, good luck man.
A sky mushroom which is interestingly enough a part of the work in progress.

mmmmm, mushrooms
Couldn't it be a marshmellow cloud? Pleeeease! ;D
It could be...
Working on lighting tests here but still lacking those dark edges.
Additional adjustments need to be tested and still working out the anvil tops aka thunderheads.
I am sure you are looking for "that one effect", but the last two are beautiful clouds.
I am somewhat puzzled by some of the Easy cloud patterns. The low lying cloud is Stratocumulus using full coverage but with a puzzling separation of noisy billowy details and very bright areas. The center cloud is Cumulus using full coverage and the large-scale features look a bit puzzling as I was hoping for a more tight pattern with less large-scale feature gaps. The noisy billowy details from the Stratocumulus is more what I have in mind for the Cumulus Congestus type cloud.
They are a tough nut to crack but hopefully the update that I thought was in like December but that's passed, will include the more fleshed out options promised.
Indeed they are, however for now I would like to have the Cumulonimbus clouds at a point of being satisfactory.

It looks as though your voxel buffer resolution is much, much too low for the density of your cloud. This is what's causing such large scale bright areas and dark areas which don't correspond to the detail in the clouds. The voxels are spread out over the localisation region, so keep that as small as you can and then increase the number of voxels if you're stil not getting enough detail in the scattered light.

That seems to be working little by little. The voxels were at 30 and I increased them to 90. I recall doing this before and Terragen crashed so I have to be careful how high I can go.
Yeah, that's why it's important to keep the cloud (localisation radius) as small as possible to get the most use out of the voxels. Going from 30 million to 90 million voxels will only make a small visual difference.
You'll get better results if you don't try to make one cloud layer go all the way to the horizon. You can always use a separate layer for the distant clouds.
The local radius is at 50,000 meters. I suppose I can cut that down more. Thank you for the help.
This is set at 75 million voxels and it appears to look fairly good. At 50 million voxels, I started seeing the issue reappear. The localization radius was left at 50,000 meters.
Quite a difference indeed.
The left side is set at 30 million voxels and the right side is set at 75 million voxels.

Yup for where you seem to be heading you've hit the 'sweet spot' at 75 million
Very confusing!
The big difference between the first, second and third renders. The lighting in Stratocumulus test 1.png with 75 million voxels is not showing much internal scattering, just a broad ambience, so I thought you would need to increase resolution in some way. But the latest 75 million voxel render is doing much better. It looks like some other settings changed, perhaps the density. If they didn't, then I don't really understand what's happening.

For Stratocumulus test 1.png, I changed the Sun glow amount and Sun glow power to a lower setting.
Mammatus type clouds as they can appear underneath the Cumulonimbus cloud base and as well as underneath the anvil itself.
Those are really nice.
Those clouds usually mean something is gonna change, but they are fascinating to watch. Beautifully done.
Is that TG?? If so it's the best mammatus I've seen! Please share. :D
- Oshyan
Those clouds look great.
I intend to share this soon.
A more stormy type of Mammatus cloud.
Wow, cool! Agree with Oshyan. I'm not sure if anyone has ever made (recognizable) Mammatus clouds at all here.
AP the Cloud Walker...awesome, can't wait for the share....Be nice if this could be incorporated into the TG cloud selector
There will be a set when I am finished.
They're awesome, good to hear. Thanks in advance.
