Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Vortex
I need to make a spiraling vortex of clouds and asteroids for my camera to fly through so I thought, what better than to use a Vortex field. Only the thing is I can't come up with any settings that are any good. Everything I try, the vortex starts off spiraling nicely, but the radius quickly expands exponentially and gets huge. The docs claim you can keep that from happening by setting the conserve value to 0, but what that does is bunch all of the particles up into a ver very tight spiral like a pole and then spins them in that form.
Does anyone know of any good tutorials or can you offer me any advice here.
Thanks,

In the docs it says:
Tip:
If you use a vortex field with a particle object, you can set the Conserve attribute of the particle object to influence of the motion. If you set Conserve to 0, the particle object moves in a circular motion. If you set Conserve greater than 0, you get a spiraling motion.
I believe I tried to create a glaxy type of effect some time ago, and I had that same problem too.
My problem, If I can remember, was that I had my Vortex magnitude set too high, along with other random incorrect settings....
I'll try this later today when I have more time, and I'll post my settings to make it work
Cool?
PS: But I think Mike it right, in that all you "should" have to do is:
- emit some particles
- set initial state for selected when you are happy with the amount of particles
- rewind
- set particle conserve value to .95, or lower, depending on how you want it.
- Apply the Vortex field to the selected particle shape.
- Play with the Magniude to get the spin you want.
- Add other fields to taste.
Again, I'll try it tonight, and post my results, ans settings for this, as this has always made me mad as well
