This thread is amazing, folks!

Hows it going Volker? Long time no see. :)

Mr_L.: i've got a question for you,too.When rebuilding your nodes
i have to swap the first two connections on the conditional scalar
to get the desired result (see attachment) and i can't figure out
what is going wrong here.Do you have an idea or do you see my
possible mistake?Or might it be a glitch? ???

Edit:forgot to say that this goes for the geometrical clouds too.

My guess is that since you swaped the conditional shader's output, you've now got clouds everywhere except where the cone is. So you got an infinit cloud with a cone-shaped hole in it....

I changed the test setting of my conditional shader to test for Less Than.  If you are using a default Conditional It will be testing for Greater Than. You have produced the same result by reversing the order of the values being compared.  You could have also achieved the same thing by swapping the outputs.

Yes correct.

When the conditional shader makes its test it splits the cloud layer into two regions, in this case a funnel shape,. One inside the shape and the other outside the shape, the outputs determine if you have a funnel shaped cloud or a cloud with a funnel shaped hole.

Thanks for the heads up.I was not aware of the fact that
one can change these settings.

Booleans?

That's super cool! ;D

Beat me to it BELGIUM!  >:(

Now I'll have to go away and do something else  ;D

Where did you find Styrofoam that big? ;D
The top one looks like a Styrofoam Mother ship.

Oshyan: ;D

Mr_L.:sorry.     Belgium???
How about a Dodecahedron or an Icosahedron,that would be great! ;)

sonshine777: got me,it's actually package material from a mothership
and little moon i bought recently. ;D

HEY! Stop that before this forum get's censored!

Anyway, the problem with Dodecahedrons and icosahedrons is that they're quite dificult to describe mathamaticaly. A sphere, cone, cube or tetraeder can just use mathamatical functions. Imagine programing an dodecahedron with linear functions!

I'm pleased to see that someone knows where their towel is  ;D

Dodecahedron or Icosahedron hmmm I might have to think about that; hmmmm the program could take a while to run....

There is a wikipedia entry for the Icosahedron at http://en.wikipedia.org/wiki/Icosahedron and the Dodecahedron at http://en.wikipedia.org/wiki/Dodecahedron
if those are a help.

Regards to you.

As for the polyhedrons: too complicated? ;D nevermind,it's not important.

Hmmm,why is it so delicate to mention the home of french fries?I'm afraid
my english is too limited. :( ;)
