"steam-train" smoke effects

[zkydz]

"Cartoon Steam" kinda throwing darts at a big board there, eh? What did you have in mind? can't expect a proper reply without and example of what you want.

Year, I was lacking a bit with the info, but I'm having this Final project these days, and are so busy with it!
I made a nice particle smoke sim, but it looks "too real" to fit the invironment!

WIth the "steam-boat" effect, I was thinking of the old Disney Cartoons where the "smoke kind a exits the funnel in "balls" with a little puff...and for a little while little is coming out, and then another "ball"...etc...
Do you get the picture?

Thanks in advance...

Particle system, sphere shape, small intervals, long fade with travel made with wind, appropriate shader for cartoon effect.

I had to recently create a smoky explosion for a feature I had to jump onto at the last minute. I used afterburn to create my smoke since it has a nice toony shader int here which was quite handy to use. Basically if you enable clamped output in the afterburn renderer and then set up colour one to be a blue or black colour of the shadow and colour 2 to be a white colour for the smoke, enable raytraced shadows and up the shadow samples a bit you'll be able to make a really nice smoke shader.

The originally freelancer who was meant to work on the shot was going about it a different way in Maya by making sphere's with a cel shader on the top and blurrying it. It didn't really work, but if you don't have afterburn then something along these lines might be useful. Make a chunky bunch of spheres by making a sphere with noise on it, and then make a material with a falloff texture in the diffuse slot with a very sharp falloff curve and put a light that casts shadows into the scene. Set up as a particle system this should make a nice cartoon look.

if you check on 3dluvr.com under the maxed out section there's a few tutorials on cel shaders I've written which might help with this.

Hope that helps,
