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. Section Color group Selection Color determines the color of the effect by using three different color swatches that are matched to the three sections of the effect. A map can also be used to determine section color. Mix Mixes colors set in Radial Color and colors set in Section Color. Setting the spinner at 0 will only use values set in Radial Color while setting the spinner at 100 will only use values set in Section Color. Any value between 0 and 100 will mix between the two values. Falloff Curve Displays the Circular Falloff dialog on page 6652 in which you can set weights for the colors used in Section Color. By manipulating the Falloff Curve you can make the effect use more of one color or map than another. You can also use a map to determine the falloff when a light is used as a Lens Effects source. Radial Size group Determines the radial size around the particular Lens Effect. Clicking the Size Curve button displays the Radial Size dialog on page 6661. Using the Radial Size dialog you can create points on a line and move those points along a graph to determine where the effect should be placed around the light or object. You can also use a map to determine where the effect should be placed. A check box is used to activate the map. Lens Effects Rendering Effects | 6641
