My first attempt at big cloud structure.

Non-registered version.

neat, you may want to clowing the edging sharpness though.

Thanks for the feedback, Will.  Did you mean to write 'glowing the edge sharpness'?

How to do in TG, or do you refer to post-processing, ala PhotoShop?

TIA.

there is a thread on the general forum about this topic and might be worth a read 4 or so pages

you might get some more ideas here http://forums.planetside.co.uk/index.php?topic=34.0

King,

Your work shown on that thread looks great -- that's what I wanted to achieve.  After researching advice from Oshyan regarding how cloud settings operate, I found that my guess at keeping the sampling rate high was a mistake.  Very low edge sharpness settings (0.03 in my case) create the correct fractal wispiness of cloud structure for impressive photorealism.

I'm glad I'm taming this TG2 beast, the results appear stunning.

Here's my 2nd go at it, muchly improved:

Great improvement. The kind of clouds I'd love to achieve. The tgd file would be very appreciated to understand the fine tuning  :)

great to see you getting the hang of it... kind of the reverse I did i used lots of samples. highish density, and almost no edge sharpness

nice results srb!

Awesome clouds srb :)
Love the "glowing" edges and the consistent formations.
The cirrus layer really ads depth and realism, great!
I'm especially curious about the pattern settings, because I still don't get a hang of it, so when I'm back home I'll have a look at your file. Thanks for sharing!

here is some experimenting.. it doesn't look too good in the render because i had to lower the samples... crashed after 35hrs originally

the water is a water shader into alpine shader.. also experimenting

also included some cloud node tgc so you can plug these into any render you want

Quality could be better indeed, I'm also watching it on a stone-age monitor here at work, but as far as I can see this looks pretty impressive!
Definitely will took a look at it at home.
This took 35 hrs to render? Unbelievabl(y slow)e...  ;D

Nice work and thanks for sharing!

I had samples turned up to 384 each cloud layer... and tg2 died slowly untill xp stopped working so that render was done at clouds at 20-30 samples

awesome clouds...good to see the difference in the images really, just tweak a few settings and the results are outstanding. bravo.
