I haven't been able to find one. I have sent an email to Khang Nguyen. He wrote these programs and another called hair. He used to log into renderosity under the name geese. Hasn't been here in a couple of years.

Back on the main subject. You could also use scatter to distribute trees and sticks in your tornado funnel. Scatter flaming rocks from your volcano. Distribute spheres you could apply cloud textures to. Bryce randomize tool isn't that random and things spread out from the center. You can't keep things from going places. You can only delete them afterword.

Like the others have said Bryce can do a lot of things like dark clouds or mats for rain. Bryce does not have particles or physics. In Maya you can paint grass on a surface and make it sway in the wind. Programs like that start at a couple of thousand dollars and go up if you add fire, smoke, water, cloth, etc. You get what you pay for.
