VNgen scenes come in two flavors: backgrounds and foregrounds. Both exist as sprite resources and appear beneath UI elements such as textboxes and text, but as their names imply, backgrounds appear behind characters while foregrounds appear in front of them.
While a single background is all that's necessary to set the stage for an entire scene, it is recommended to use multiple layers of both types for maximum effect. This becomes especially powerful when combined with perspective functions. In addition, foregrounds are quite useful for scene effects such as fades to black.
In this section we'll examine available scene actions covering five basic operations: create, modify, replace, destroy, and animate.
