Size Determines the size of the effect. Intensity Controls the overall brightness and opacity of the individual effect. Higher values produce a bright, more opaque effect, and lower values produces a dim, transparent effect. Num Specifies the overall number of rays that appear in the lens flare. Rays are randomly spaced around the radius. Angle Specifies the angle for the rays. You can enter both positive and negative values so, when animated, the rays rotate in a clockwise or counterclockwise direction. Sharp Specifies the overall sharpness of the rays. Higher numbers produce crisp, clean, and clear rays. Lower numbers produce more of a secondary glow look. Range=0 to 10. Glow Behind Gives the effect the ability to be displayed behind objects in your 3ds Max scene. Occlusion Determines how much the Lens Effects Scene Occlusion parameters will affect the particular effect. The value entered determines what percentage of occlusion set in the Lens Effects Globals panel will be applied. Squeeze Determines whether the effect will be squeezed. When activated, the effect will be squeezed according to Lens Effects Globals under the Parameters panel in the Squeeze spinner. Use Source Color Mixes the source color of the light or object you are applying the effect to and the color or mapping set in the Radial Color or Circular Color parameters. A value of 0 uses only the values set in the Radial Color and Circular Color parameters while a value of 100 uses only the light or objects source color. Any value between 0 and 100 will render a mix between the source color and the effect's color parameters. Radial Color group The Radial Color settings affect the inner and outer colors of the effect. You can set the color swatches to set the inner and outer colors of the Lens Effect. You can also use bitmaps such as Gradient or Cellular to determine the radial color. Falloff Curve Displays the Radial Falloff dialog on page 6658 in which you can set weights for the colors used in Radial Color. By manipulating the Falloff Curve you can make the effect use more of one color or map than the other. You can also use a map to determine the falloff when a light is used as a Lens Effects source. 6618 | Chapter 21 Effects and Environments
