Fumarole

Thanks J.
More than one layer was my assumption.

And I don't think it's possible to get a widened top by just rotating a SSS btw.

"And I don't think it's possible to get a widened top by just rotating a SSS btw." Yes, those are my thoughts also. Looks like we'll be here for awhile.

[choronr]

Intrigued by Inky's fumarole, I did some research.

Did you have to do a lot of density reseeding to achieve this shape?

[Dune]

It is possible with the SSS, why don't you guys just try it? Simpler than a stack of clouds.

[j meyer]

I've tried it several times with transform shader and what not,wasted hours that
kept me from doing the stuff I should do.
But most likely I'm just too stupid again.

Very nice result Ulco. I think we are many who would like to know how achieved such smoke. The explanations seem incomplete for most of enter us. You would not be interested in making a final file that you would sell on NWDA for example. I'd buyer.

[choronr]

I'm more patient than smart ...bad combination; but, I'll keep on trying.

You're not alone in the *stupid today* camp Jochen...wasted far too much time. stolen from my music on this....maybe next week I'll take another stab at it....

I understand you choronr but personally I'm not very patient because I know my limits a long time with all that is a little complex with terragen. In my case , even though it seems to me that it is EXTREMELY easy to do this type of smoke if I did not tgd any verbal or written explanation appears just like gibberish.

Now all that is over... I can disclose:
I used multiple cloud layers, all restricted, using larger diameter for each progressively higher layer, the core of the geyser is a modded version of Ulco's volcanic plume/ cloud column... Though barely visible, so you could do without it.
My hdd is playing up big time, which is not good, but if possible I will experiment more and post a clip....
Cheers folks,
Away for a beer

Thank you Jason !!!

I'll give you another hint (I'd rather sell my railroad setup than this  )...... use the X for rotating the triangular (!) SSS by -90º and raise it a little(90m), depending on the sizes (100-250 is good as a start) .... then merge (multiply) another rotation of this rotation, but this time by 90º over Y.

Who will have found it the first?........

[ADE]

now I see this, I was experimenting on a similar theme this morning trying to get the same thing so I placed a vortex warp shader and a transform too...but got unexpected results, originally I was aiming for a rainbow : O

posted a few in facebook as capture snips, so I cannot post images here on what I did

[j meyer]

This is what I get doing what you suggested.

I'm lost with this explanation. Are you saying the ..."use the X for rotating the triangle...". Do you mean the X in the Density shader? The only X Y and Z us in the Density shader. And, my SSS is a rectangle, not a triangle. Maybe it is a second SSS overlaying the first in such a way as to form a triangle - a geometry trick?

BTW, I'll be ordering the railroad setup.

[Dune]

The X in the transform shader (because that's where you rotate), and the SSS has much more options than just a rectangle. Try polygon and set the number of cornerpoints to 3.... triangle.

Come on guys, you can do it
