Moving Clouds
I tried to use smoke to create a puff of smoke and the effect didn't
look real because the IPAS module makes the smoke look like it's in a
bottle or any shapped glass container. Real clouds don't have any
bounding borders. You could retouch the image in photostyler but if
it's a flic that could be a bear. Depending on your layout you could
bound the smoke beyond the image safe zone (overscan). I was told
that smoke.sxp was designed to simulate a light beam through a fog or
smoke.
