| You'll need to use a displacement effect. Turbulent Displace will make the image flap, but it will do so uniformly, which might not be desirable (there are probably parts you want to flap more than others). More complicated, but more flexible, is a displa
cement map. You create a nested comp with some animated fractal noise in it, and use a 50% gray solid and masks (inside the nested comp, on top of the fractal noise) to define the areas you want to flap less (50% gray = no displacement). This will allow y
ou to precisely control which parts of the clothing flap most (say, coat-tail and shoelaces) and which don't flap at all. You then use this nested comp as the source for a displacement map effect.
Whichever way you go, the key to a "flapping in the wind" effect is to animate the transform parameters of the fractal (with Turbulent Displace, the fractal is built into the effect, with Displacement Map, it is the Fractal Noise you created). Move this p
arameter upward very fast to indicate the a strong wind from below.
And, of course, you'll want the stuff that flaps on its own layer, separate from the stuff that doesn't flap, i.e. put the clothing and hair on a separate layer from the character's body.
