Odd, I tested image attachments and they indeed were working. But I see they don't in your post. Not sure why. Sorry to bring this a bit off-topic, just wanted to note that we're looking into this. Attaching an image for a test...

Seems to work fine now, I edited my post to fix the image display.

cheers Martin, I have a couple of cloud experiments on the go, it will be interesting to see what I can glean from this!

nice cloud nodes DandelO!  :)
 these make me want to get back to using TG2!

A simple and basic column of warped cloud for volcanoes and such. Many settings to play with..... and stuff like mixing two of these with different cloud colors.

Here's a thing I was playing with and thought it would be a good idea to tidy it up to make it easily usable as a clipfile. It provides up to 3 extra levels of added detail based on Voronoi noise to the cloud layer. This might be useful as another approach at creating the 'mackerel' effect in the sky as it adds continually decreasing cells to the layer. Further warping and/or stretching(not included) could probably be tweaked to make some cool 'herringbone' effects, too. Have a play.

The instructions(are also in a note node in the internal network of 'Voronoi Cloud Shader') are as follows;

Main Network View.

The cloud seed and distribution controls, 'Density Fractal 01', is found beside the cloud layer node. You can use random seeds until you have a nice form that suits your scene. I have made a nice default setting. You can adjust all parameters of this node to your own taste, so it has been left easily accesible in the main network view.
As well as providing seed and coverage functions, 'Density fractal 01' is also the mask for the following levels of Voronoi detail.
'Density Fractal 01' should NOT be connected directly to the cloud layer, it is supposed to be that way.

The node 'Voronoi Cloud Shader' should be plugged into the density fractal input of the cloud layer node.
_________________

Internal Network View('Voronoi Cloud Shader' node).

Choose an output from 'Level 1', 'Level 2' or 'Level 3'. Plug it into the 'colour function' input of 'Voronoi Shader'. Each ascending level of Voronoi functions raise cloud detail by adding smaller scales of cells which subdivide the level directly below themselves. Consequently, the higher the function level, the longer the render time.

Level 1 =  Adds 750m base-cells to the cloud layer.
Level 2 = Adds a subdivision level of 4 to the base-cells.
Level 3 = Adds a subdivision level of 8(of the base-cells) to level 2.

Lastly, there is a node in the internal network called 'Warper'. This does just that, warps the cloud layer to remove the visible straight edges from the default Voronoi cells. It is scaled to match the preset Voronoi scales and shouldn't require any further editing.
_______________


'Level 1,2 or 3' nodes plug into the 'Voronoi Shader' as shown in the internal network screenshot, default settings are 'Level 3' - Full Voronoi settings;

The clip file defaults are 'Voronoi Clouds_b - Level 3'.

This is an amazing picture. I've seen the daylight version of this as well. Oshyan Is this your work?

They just issued a tornado warning and said to stay away from windows. Does that mean I can't use my computer?

Did DandelO's rar attachment for the tgc clips get lost/deleted from his message (see page 12 of this thread)? I was about to try diving into voronoi clouds myself, and this would be a massive boost.

Thanks,

nice job Allen, for the terminator zone, try changing to a default atmosphere and this settings:
Bluesky height: 7000
haze exp height: 1000
ceiling adjust: 8
in the lighting (cloud node)
change the enviro light to 1
the enviro light tint to 0.1125
and cloud altitude to 8000
this is only for a better aesthetics.
 ;)
Hmmm, what version of Terragen use god?

Cloud coverage doesn't always work good if you have your cloud fractal masked. Did you try working on the fractal variation and clumping itself? Perhaps adding a bias scalar plus some constant node or even (theoretically) a PF? Just thought of the last sentence, never tried a bias here. And/or using the gamma adjustment in the cloud node?

Hi Allen, if you ask me, in your 1st Global cloud test1, the picture above looked pretty
good to me, I guess in his last test, you have found a middle point in the result.

Here is the tgc file (clip) for my cloud setup. Just connect the atmosphere to the altocumulous node and the altocumulous node to the Planet node where the atmosphere node was connected.

The density fractal will control the amount of vertical 'stretching' by changing the warp slider value in the warp tab.


Thanks Henry, I really like this and had forgotten I downloaded it...well built and versatile. PS ought to collect a bunch of these and have a preset pack that installs or comes with the dl...like the one now but stuff culled from here in File Sharing. I figger any one of us would be honoured to have their .tgc included....just thinkin again...a baaaaad sign for sure, hee hee hee
