vray fog with 2D texture
show user profile  cbflex
Is it possible somehow to take a 2D texture and apply it as the fog color or density in vray environment fog?

So, I'm trying to recreate Saturn's belt in a efficient way. I did some research. The belt is basically mostly ice water, though particles consist of huge boulders of ice and dust as well...
I've created already a large ring of rock particles using the position object thing in Pflow and setting it work on a grayscale basis.
Even though I already have a lot of rocks, they don't happen to cover all the small thin lines in the saturns rings, and i think my computer has already reached it's particle limit in max. So I was thinking of creating saturns ring using particles of large size as well as a vray fog. However, I can't create the vray fog because I can't apply the ring texture to neither the fog density nor the fog color. I'm not quite sure how I'm going to do this.
My goal is to be able to zoom from out of the rings (seeing Saturn the way we see it on Earth), and zoom in to it where I can see ever individual rock and dust particle.

you might wanna check krakatoa.
Krakatoa can cache a couple of hundreds of millions of particles. (do bear in mind massive file sizes)


Normal pflow you can get up to about 8 million particles per flow, if necessary you can use multiple flows with different position seeds.(not advisable but it works)

I read in the vray manual, that this is possible.

They used gradiant ramp in the fog color parameters. I tried recreating their scene but I have no luck in it. How did they do it?
