Integrating some ideas for Cumulus cloud tests with various changes in mind.
That looks promising.
I am doing some more lighting adjustments, trying to make it look more real. It looks somewhat milky. Adjusting more bumpiness. I managed to rid the flat cloud tops by figuring it was a contrast issue all this time. The cloud tops look as clouds of this type should look. It took years to figure that problem out. :P
Interesting. Maybe soften the base a bit more?
They do look to hard edged. I will post an update later.
Looks like badly de-snowed driveway. ;)
nice billows!
:)
More roughness but still not quite there.
Less sharpness perhaps...?
The sharpness is at 9, not too sharp for dense Cumulus clouds. The cloud convection causing the billowy features always tend to be sharper in density. I am adjusting the roughness a bit less. It is a bit too broken up and the billows are less prominent which is not wanted.
Have you used color adjust shaders yet to manipulate contrast and coverage?
Not yet as everything was adjusted within the Density fractal shader.
Using a Perlin ridge noise for a more turbulent look.
I like test 2 more. How does it look when the clouds are less dense ?
Test 2 is a bit too broken up so there needs to be a satisfactory in-between rough and smooth. Density has yet to be tested.
Closer to a compromise between tight billowy and broken up. The lighting looks better for this one, i think?
The top is already unbelievable good!
I don't really know what is disturbing me about the bottom of the clouds. But just an idea: Is it possible to add a couds layer with less density but minimal higher coverage some meters lower? I fantasize just a little...
Yes, I like the tops as well, the whole clouds actually. Perhaps soften the bottom more? I've done some work on clouds too lately, and found out that you can also use a surface shader with a negative black color (+input) to adjust stuff (at certain heights), and use the child input to alter the feel of the cloud. There are always new ways ;) I guess blue nodes can do the same (like bias, modula, clamp, whatever, but I'm not really good at those (at all).

Certainly, however the idea was to use as little nodes as possible here. I like a good challenge while still trying to keep it realistic. My current render should have more soft cloud bottoms.

Funny, i to was thinking what could be done with a Surface layer and the like? One idea is anvil tops for very tall thunderheads. Displace outward near and along the cloud tops somehow. I want to flatten those out when they hit stratosphere.
Less density and softer bottoms. Added some additional height.
Very nice!
Looks good.
If you try to subtract clouds (perhaps with height restraint), you'll see that some sort of opposite is added elsewhere. Has to do with clamping. Somehow the black has negative values that you don't see, but they are there, and when subtracting this will be added :o Very complicated if you look at a mess of nodes too long and have all sorts of connections. Bias is also interesting, with a fractal as bias'er. You never end playing/working.
I will have to try those ideas out soon but it sounds rather enticing.
Great exploration Chris. You've a very active mind....
Thank You.
When i get to good enough point, i would like to share the results.
Now that the contest is over, back to some cloud experiments.
