Source Point and Ray Length

| Important: When animating the Source Point slowly, the layer that Shine is applied to should be switched to high quality in order to make the Source Point sub-pixel accurate.

Source Point sets the center point for the effect, the point from where the rays shoot out. It can be placed outside the layer, but will not move farther than one layer size in each direction, as illustrated below:
Ray Length controls how far the rays shoot out. Note that this setting has no influence on render time.
