hmmmh?

This is what you get when you attach a voronoi3dBvector
(with a get position and a constant scalar) to the
density shader input of a cloud layer.The light pink
color is caused by the sun and atmo settings,but why the
other colors? Any ideas,anyone?

[dhavalmistry]

oh geez....how long did that take you to render??...

I am also interested in your terrain......

as per the colors...try rendering it with default atmosphere to see where the colors are blending and where are they mixing (if they are)

[rcallicotte]

Cool!

Must be some weird math at work, eh?   

[Mr_Lamppost]

Interesting effect 

The Voronoi 3D A Vector gives a something similar.

I wonder if this is a general case for all vectors used in this way  You get similar results if you feed the Vori A or B vectors into a colour function 

I am away to try something psychedelic with perlin.

The colour should disappear as soon as you put a 'length to scalar' or 'luminance to scalar' in between.

But somehow the colur makes sense ,-)

dhavalmistry:rendertime was34m14s,the terrain is a variation of the power
fratal with 2 color adjust nodes you requested in the other thread here with
negative displacement.
As for the color i could get rid of it already,but i thought maybe we can find
a way to utilize it to colorize the clouds.

calico:thanks

Mr_Lamppost:tried the A vector too .If you find something please post it.

Volker Harun:haven't played with these two yet,but as mentioned above i was
hoping for a coloring-clouds-method rather,so if you can make up something
please let us know.

[Volker Harun]

You have seen in the image section the Gradient Hack by Efflux et al.? It builds colours by using the Mix Colour function.

If you multiply (colour) such a Mix Colour with the clouds density shader, it might look nice

I presume that this is finally the dawn of surrealism in TG2!?! Very good find!

Attached is an image that has a saturation-glitch (red dot).

[dhavalmistry]

hey Volker....is there a way to control where and what color are being mixed??

[Volker Harun]

Well, I used here the clouds' density shader for mix control (to blend the two fractals) More dense clouds means more colour from one fractal and vice versa.

The fractals themselves have the possibility to use 2 colours (default is black and white). And of course the fractals can define some shape to mix their colours.

[dhavalmistry]

ah...thanx...will give it a atry

[Volker Harun]

In my opinion J Meyer's observation is a very powerful tool.

You see in the rough preview, how the light iluminates the 'city' very colourful. Now think to turn off the clouds' 'Primary' - they are invisible, but the light changes the colour.
Fancy illumination! I am going to love this!

[j meyer]

Thanks for the heads up and the nodes graph Volker.
I'm off for some more surreal experiments.

[Volker Harun]

Now I know who this (1 hidden user) is

[j meyer]

  but i noticed 2 more at least

Well umh,that took me really out there,heehee.
Lucy in the sky...

[old_blaggard]

Very cool .
