Ring Chapter 46: Using Atmospheric and Render Effects
The Ring Lens Effect is also circular and includes all the same controls and settings as the Glow Lens Effect.
The only additional values are the Plane and Thickness values. The Plane value positions the Ring center
relative to the center of the screen, and the Thickness value determines the width of the Ring’s band.
Figure 46.26 shows several Ring effects with various Thickness values (from left to right): 1, 3, 6, 12, and 24.

Ring effects can vary in thickness.

Ray
The Ray Lens Effect emits bright, semitransparent rays in all directions from the source. It also uses the
same settings as the Glow effect, except for the Num (Number) and Sharp values. The Num value is the
number of rays, and the Sharp value can range from 0 to 10 and determines how blurry the rays are.
Figure 46.27 shows the Ray effect applied to a simple Omni light with increasing Num values: 6, 12, 50,
100, and 200. Notice that the rays aren’t symmetrical and are randomly placed.
