Hi,
as promised here's a little teaser from the "Cumulus Atmosphere Pack".
This tgd has been tuned specifically for close ups on the big clouds. You can see all the little details it has, plus a few whispy strands here and there. Other than that, I'll let the image speak for itself:

Looks like a chemical explosion.
:o awesome! :o
I think you're going to make many many of us VERY happy ::)
very good job on those clouds !!!
Looking good! I would personally prefer a little less wispiness on the edges, but regardless, they are the closest I've ever seen someone come to Luc's.
Thanks guys!
O-B: it's really easy to reduce the whispiness if you don't like it. They way I've implemented this you will have full control over how many details you wish to see and how soft or strong they appear. The example image was based on my preferences, of course, but it doesn't have to be like that. The idea is that I wanted to go beyond the Luc cloud technique, by providing "switches" for small size detail and detail whispiness. In order to better demonstrate that difference, I have created a view and scene similar to one of Luc's (as you may have noticed)
Cheers,
Frank
Excellent Franck :)
Very similar (maybe even better) to my clouds v2 (http://lucbianco.free.fr/jalbum/Terragen%202/2007/slides/TGD823.jpg)

I'm wondering every time when I look at those clouds - how many samples (atmo/clouds) are needed in order to render without noise :D

that would be atmo 60 and cloud ~700 (+/- 100, depending on the cloud)

Hi Franck
I don't know about your technic but here the basis for mine:
A density fractal (with lead in scale = 4x the feature scale) connected to a cloud layer via a colour adjust shader (gamma between 0.1 to 0.2)
But the most important is "master" the fractal seed ... your technic will be a winner if you can give a "wanted" shape of the overall cloud whatever the seed value !
For that I have find a workaround (by playing with distance shader) in my clouds v4 (storm over islands picture http://lucbianco.free.fr/jalbum/Terragen%202/2008/slides/TGD906.jpg) but it is still not very accurate.

yes, that's similar to my setup, too. However, the fine tuning is the hardest part.
The right seed is still important, but my technique has split the "chance" factor in three adjustable parts, so that there is some level of control on that chance factor.
Cheers,
Frank
60/700 that's quite a lot. Right now I'm rendering some cumulus with 128/500. I'll show my results at the forum right after it's finished rendering.
What about acceleration cache? Do you always turn it off for rendering such clouds?

Get the mop and bucket. Calico's going to wet himself! ::)

He's not the only one! It's great to see and have access to work by both of you. Thanks a whole bunch!
Hi
I had the chance to look at Franck's pack, it is a very powerfull set-up to create easily spectacular meta-clouds and tune them easily.
luc
thanks for sharing the file !
that's going to be crazy clouds time with you two guys sharing files and info ^^
Yes, I'm looking forward to you guys astound us all with your great art!

Thanks Luc! I'll let you know when I use it.
Nice. ;D
thanks Frank and Luc. I have gained so much insight from Franks tutorial and Luc's gift. They both cleared up a lot.

Fantastic work guys. Many thanks for sharing.

Many thanks for sharing your settings.
Additional knowledge has been absorbed and incorporated:
As a cultural anthropology student also with some experience in sociology I'm totally impressed on social capital level in those forums. This sharing of own experience and knowledge by distributing not only pictures but also techniques is fascinating. That's a... social aspect of using TG2 - could be used as a part of Terragen advertisement ;-)
Hi,
yes,indeed,thanks for sharing the tgd with your settings Luc.
Thanks ... alot
Thanks to the both of you Frank and Luc ...as I said earlier, this opens a new plateau in TG2.
:o
Thanks Luc. Very generous.
And thank you, Frank. Though I paid a little for your two packs, what I learn will be priceless.

A late Christmas gift from Luc, thankyou. I think this is a first as well isn't it? With Frank and Luc both contributing to this we have a treat in this thread.....i've been making notes.
I see a bear of some sort in those cumulus clouds. :)
I've been a way from Terragen for a while... But now I'm back and I got to say "Thanks" to Luc and Frank for the valuable info shared.... so.... THANKS.
as a beginner with tg2, i was near despair when i finally found this thread where i now can look how the pro's do it ;)
thank you so much for sharing this. really great!
