Hi,
I'm looking for some help on making chimney smoke. I'd like to make the smoke coming out of a chimney slowly drifti to the right side of the screen in a natural undulating way. I created a stream of smoke using CC Particle World and Radial fast blur that looks okay, but I can't figure out how to make it blow gradually to the the right in the curvy wavy way that smoke drifts. Can anyone help me or point me to a tutorial? I don't have any of the 3rd party plugins for AE, so I'd love to be able to do this with what come stock in AE CS5.
Thanks. Ellen

Use puppet tool- I remember a tutorial that described how to make a wind tunnel using particles and puppet tool, try searching the cow for that and use the same technique.

Thanks. I'll see what I can find. I did try a couple of other warp things like DE Freeform, but it didn't really work the way I wanted.

Try using particle playground and some layer maps, they can affect position.

I've been where you've been and if you want realistic, manipulable, silky smoke (not puffy smoke) you're going to have to bite the bullet and dl particular. There's no way around it, at least in my searching. If you decide to download it just do this and add some wind.

Yup, wind is actually an option in the particular settings. Awesome right?

Another vote for Particular. Like Eddy said, it makes the physics easy, and the new self-shadowing feature is perfect for smoke.

Played with this some more using particle playground(comes with AE) with these results(I can't get it to play in this post, but if you click the chimney smoke link it plays):

Chimmney Smoke



Here are the settings, can't see it, but I used wiggle on the particles per second "wiggle(4,40)---Main Comp:

Well I can't afford particular right now, so I'm going to give John's idea a try. Thanks John. I prefer the smoke to go a little slower, but I've already got that part figured out. I've never used layer maps, but I'm sure I can find a tutorial somewhere.
