creating convincing cig smoke?

[mushroomgod]

wiro has a very nifty tut on his site ;)

i dont think this one is really going to work for the goal thingy but for cig-smoke, i had very good results with the following setup:

- do the particles as points or streaks with very short length
- make the conserve value to something between 0.5 and 0.75
- create a gravitiy for the rise
- create a turbulence with low frequency for the twirl
- animate the phase of the turbulence with the time

now go to post (e.g. shake)
- average the frames from the animation to have the streaky and round look of the smoke by about 10-20 frames (a 10-20 frames blend that is)
- blur the result

that gives cool results for me

cheers

edit: you will need strong fields the lower the conserve value of the particles is but the look will be what you want
and i mean the particles to be hardware rendered.. use a lot but very small ones (size 1) and slightly differ them in color with a rgbPP expression

wiro's smoke, as it says in the tutorial description, is not animatable.

cheers all. Have just searched and found a post by bigfatmelon on a previous enquiry about the same effect so I'm just playing with that one now.

thanks again for speedy response!
