I know this discussion already happened before, but none the answers I would have liked to have been answered were answered, or maybe the answers are to difficult to answer.
So....
I would like to do this effect in one of my films over and over again, however, I will tweak the effect so it is not the same. But essentially every test I have done with fluids has not given me the effect I desired.
How do I make the fluid effect look more like the night crawler effect. I know that is a broad question. But have my effect have more of a defined wispy smoke look. Like what parameters would I have to toggle with to get that effect- shadow-opacity. shadow-transparency. I'm not really sure.
How to make the fluid have more detail within it?, because my fluid here looks like I blurred it and it has a blobby look to it, not like smoke.
So if anyone can help me out at all. It will be greatly appreciated.
Thank you very much for your time and consideration.

I would say you dont use fluids for this but rather particles taht possibly emit fluids. Personally id go all particles. But say you wanted to do this with fluids then atke a look at overburn that can be found here:

More voxels more rendering time in the raymarch. In any case the kind of effect they do in the movies is usally the work of single man for 3-6 months to perfect the look and its not easy t do it in 2 minutes.

Thanks for the advice. But unless i am mistaken, isn't overburn only for 3ds max? But I can be totally wrong about that.
Another thing is, I know a little bit more about fluids than I do particles so I would like to still work with fluids. I'm not really sure how to emit fluids from particles.
Also, I'm pretty much just trying to get the look of the thin wispy smoke, the movement of the effect is not my priority. However, can this still not be done in fluids? What I am asking is there some sort of parameter or parameters that I should try and fiddle around with to get the thin wispy smoke look?
Thanks for the advice and if you know any type of material that will help me more with particles that would be great.

Thats afterburn. Overburn is a script thet makes maya particles work with fluids.

Well, you know so allmost nothing that the difference is minimal.

Yes but you need a dense containers and really understand how th fluid works. Its also expensive to have all those very thin tendrils of smoke. Overburn prettymuch solves this problem.

Hit f1, then go to shipkovs site above, then duncans blog, and read the few tutorials on this site.
There snot much mysticism to the particle solver just a lot of thinking involved.
I noticed a lot of people use Perter Shipkov's script still, which is cool but what surprises me is how many people don't understand how it works. I did a few video tutorials, one on my site you can check out (they're all free)
anyway I think the particles emitting fluids would be the way to go... if you really study that effect it's not THAT hard it's very fast and the camera has quite a bit of motion blur. The needs to be some color emission so that might be a bit of a challenge but also might be half the fun.

Thanks for the replys, yea i read the page on overburn and didn't really understand it. But i will take a look at your tutorials and give it a shot.

Hey man,
Great tutorials. I love the jokes and sarcasm. However, I really got lost throughout the explanation of the whole particles emiting fluid shaders (overburn).
But I then took a look at your transparency talk which cleared up a lot of my questions and helped me to get greater detailed fluids. (Also with the help of your Pyrothechnics DVD)
So I will experiment with different things and see what I come up with for the teleport effect.
Thanks, Yeah the overburn technique doesn't emit fluids but uses the fluid shader on the cloud particle. So if you went into it thinking that you might have gotten confused.
