FuTz is right Plugin Pac functionality is offered under the Video 2d plugins in Wax.
Shatter is available under both 2d and 3d plugins in Wax.
Shatter under the 3d plugins can be used to achieve complex transition results because you can manipulate the A/B host media tracks by mapping either or both videos to 3d objects and use the various plugins.
If you use Wax 2.0 Check my website: Here
In page 9 there is a preview of the Shatter presets.
You can download the presets package and selectively install any Transitions/Effects you like to use in Vegas.
