DIstortion lenses

Distortion lenses can provide very interesting effects, but animating them can quickly increase the file size of your exported SWF. Using a lower frame rate causes LiveMotion to generate fewer bitmaps, and using a very low per-object export setting with a distortion lens can reduce file size without compromising the visual quality (after all, each image is visible for only a fraction of a second). You can also use hold keyframes on the distortion characteristics, in conjunction with regular keyframes on opacity keyframes, to fade between versions of the lens. In this case, LiveMotion generates bitmaps only where the distortion characteristics change.
