Cloud Help

[eollila]

Does anyone know if it is possible to make a single cumulus cloud? Any help would be much appreciated!

That's actually not really possible, yet. I know I'm sounding fuzzy, however the concept of a "hero cloud" has not yet been implemented as such. There are ways, though, to create a mask for the density fractal, based on an image map. However, this concept bears a few issues for the renderer (strange lines in the clouds), and making the image map is tricky, too.

What you could try is to create an image map, all black and the place for the hero cloud is white. You will use this as a masking blend shader (xz projection with the right scale and placement) for a density shader, which in turn only creates color in the white region. So far as the theory. I have tried that once and had issues, but I don't exactly remember which. Maybe you're more successful.

Here's a tutorial on how to this:

Its most definitely possible.  Thats how you create thunderheads and such.

that looks amazing, but how on earht did you do it?

Um... wow!  Details?  Explanations?

Thanks for the compliments 

The clouds are isolated via a simple image map I created in photoshop.  There are about 4 layers of clouds here.  I have a higher resolution version rendering now, which I'll post when done.

I've also been working on cirrus clouds, and they are coming out nicely as well.

Hey thanks for all the replies, they really helped    I can't read German..but the pictures explained it enough anyways. By the way, awesome website moodflow.

Thanks for the compliments!  Its a bit dated, but still has some decent stuff (atleast thats what the therapist tells me).

Ah, image maps and mutliple layers.  Now it all becomes clear .

Heck ya!  Whatever it takes to get the job done.  You know pro studios and artists go that same route too

Yeah... I'm still kind of stuck in that purist mindset of wanting to only use scalable and universally useable fractals .

Thanks to your mentality, I've been learning a lot more about TG2.  Of course, there are others who hold true to this idea and I think it helps.
