Here's the atmo for Nice Day in Dystopia, 0003 is top light and 0002 is facing the camera. Have fun.

This is a TG4 file, sorry to users of earlier versions.

That would be a TG4 file, Bobby?

Very nice. Thanks for sharing.

A pleasure to share back with one who's added so much to my TG knowledge...

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;
[attachimg=1]

The clip file defaults are 'Voronoi Clouds_b - Level 3'.
Voronoi Clouds_a
[attachimg=2]
Voronoi Clouds_b
[attachimg=3]

Cheers! :)


@Dandelo  Do you have this as a clip file available to download anywhere?  It looks a like a good system to learn.

good luck on that, he hasn't, according to his profile, been active here since 2015.
