Effect Overlay

Some effects can be overlaid on the background of another effect. To use overlay, set up segments with overlapping pixels. The overlay effect must be playing on the segment with the higher id. If the Overlay option is checked, the background will not be painted and the effect from the lower segment will be displayed.

To aid in showing where colors vs palettes are used, all effects are rendered with the Party palette
and the colors:
Primary (Fx)
(or black) Secondary (Bg)
Tertiary (Cs).
For 2D effects the background (secondary) color is set to black.
