Not sure if this is the right place to post this but i'm wondering if it is possible to make smoke follow the curves of an object. I've tried and it does follow the curve a little bit but tends to wander, i'm thinking zero-gravity will help but i'm not sure i can make such a machine in a few hours.
Any tips on coaxing smoke round the curves of an object? i'm not asking it to fall again, just rising around minor curves.
You could try an additional flow of air in the direction you require maybe from a low speed fan or even the convection current from a heater.. it might be a direction to try
yeah i was thinking along the lines of that (i tried blowing) but it was way too strong.. i'll see if i have something that would gently blow it along...
Another point is to duct the air into a narrow slot this will control the flow for longer distances but its still a case of trying to balance flow with the lowest possible air velocity to minimise turbulance..
Build the face as a three dimensional box with a black front and place it in front of a black background. With good lighting, you could create smoke beneath the box, and it will flow around as it rises while the box disappears into the background.
If you tilt the object in a way that makes the path that the smoke should follow more in the ceiling (top), then the smoke will be forced to go along the curve.
For instance, if you want the smoke to follow my face curves, instead of look ahead, I should look a little (45º) down to the floor, so the curves stay on right-top of the shoot and the smoke will tend to follow.
Of course tilt the camera too, so the final efect is ok.

simple ideas are always the best! i feel stupid for not thinking of that! lol
