Cumulonimbus test

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.

[AP]

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.

[AP]

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.

[Matt]

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.

[Matt]

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.

[AP]

The local radius is at 50,000 meters. I suppose I can cut that down more. Thank you for the help.

[AP]

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.

[Dune]

Quite a difference indeed.

[AP]

The left side is set at 30 million voxels and the right side is set at 75 million voxels.

[bobbystahr]

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

[Matt]

Very confusing!
