2012 movie fireball and smoke effect

hi everyone,

i'm sure that everyone in here have seen the theatrical trailer from the 2012 movie, so i enjoyed a lot this trailer especially the fluids effect (thanks Digital Domain ) so i would like to reproduce some fireball with this appearence and the smoke clouds beetwen them,
ok i know that is a lot of work and i'm not saying that i can do the same thing
but if anyone can help me for making an effect colse to what i would like to do it will be very cool, and especially for the render of it, so much question ithout answers, how can i make the fireball burning at her head in all her trajectory and how can i obtain this kind of smoke for the trail, i made some test but nothing interessant (bad color, bad density, and a kind of stairs in the border of it, and the head is burning only when i put the incandescence at " -Y " ath the end of the trajectory), i never worked with fluids effect but i would like to know more about them for making explosion and others funny things...

thanks for your help

here's some screen of the trailer to give you the reference i'm talking about...







and here's the tests i've done

this might help you, I did a tutorial on something very similar if not exactly what you are trying to do.

I just did a test of that look in Maya 2009 using fluids:
vimeo vid here

scene file here

However, I would try Destruct007's video tutorial on the overburn technique first. You'll know a lot more about the technique after the video (my file comes without much explanation). Second, particles don't have to sim for eons. Third, fluids are just difficult sometimes (particles won't usually blow up on you and kill your dog).

hey shawn,

i tried to understand your scene file but it doesn't work, the simulation doesn't begin i have just the rock falling down, maybe i've done a bad manip.?
so i don't understand why you have 3 emitters (don't forget that i'm a newbie in dynamics ^^ ) and what is the interest of the volume axis, is it parenting with the rock or with the 2 emitters?
in my older test the emitter was my meteor, is it bad?
i saw that the first emitter is far from the rock, here again i don't understand, what is it doing in your scene, and why you have 2 others emitters at the front and the side of your rock???
i know there's a lot of question but your example is so so cool and i would like to do the same thing and understand how it works..!

thks dude for your so precious help!

To use my scene, you'll probably have to select the fluid and delete the fluidNCache. I didn't upload the cache because it was 3GB! O_o

Next, set your Preferences -> Timeline -> Playback by: 0.5 (samples twice every frame) and Playback Speed: Every Frame and you should be good. You can change those preferences while working quickly by clicking the icon of the running man to the right of the timeline in the main interface (it's next to the Auto Keyframe Toggle).

Also, you'll have to cache at a matching 0.5 and save every 2 frames.

hey shauno - could you possibly upload a playblast or (gulp) a full render?

I dont have 2009 and I'm also on a low spec laptop for a couple of weeks.

looks good though mate - cheers.
