Spotlight |
![]() |
Renders an expanding beam of light between two control points. |
![]() |
|
Start | The source point of the spotlight |
End | The end point of the spotlight |
Extend | Adjustment that extends/retracts the spotlight from/to its source. |
Focus | Focuses the light effect from a puff of light, to laser-sharp. |
Falloff | The amount of falloff from the Start to the End points |
Color
|
|
Spotlight Color | Manual: The colors are set manually, below. From Start Point: The spotlight color is derived from the start point From End Point: The spotlight color is derived from the end point Blend Start to End: The spotlight color is a gradient between the start & end points. |
Color Smoothing | The amount to smooth color samples when not using Manual color mode. |
Manual Color | Sets the light color in Manual mode. |
Background Color | Sets the background color |
Fog
|
|
Fog (Enable) | Enables fog |
Fog Type | Sets the fog type. Choose from Normal or Streaks |
Fog Thickness | Controls the amount of fog affecting the spotlight. |
X Scale | Sets the horizontal fog scale, higher values yield smoother animations |
Y Scale | Sets the vertical fog scale, higher values yield smoother animations |
Scaling (Link Y to X) | When checked, the fog's Y Scale is set to the X Scale at render time, for uniform scaling. |
Detail | Controls the detail of the fog. Lower values are smoother, while higher values are more grainy. |
Offset | Moves the fog, as wind would. In Streaks mode, x rotates the fog around the light, while y moves it toward/away. |
Z-Offset | Moves the fog through the spotlight along the z-axis (toward or away from the camera). |
Shadows
|
|
Shadows (Enable) | Enables volume shadows |
Obscuration Layer | The shadow casting map. This layer determines the location and strength of shadow casting objects. The brighter the pixels in the map, the stronger a shadow is casted from them. Black pixels cast no shadow, while white pixels cast a very dense shadow. |
Source | The method to obtain source values from the Obscuration Layer. Choose from Alpha-Weighted Luminance, Luminance, or Alpha. |
Strength | Controls how quickly shadows fall off of objects in the Obscuration Layer. |
Quality | Controls the overall quality of the shadows. 100% is pixel-perfect, but usually unnecessary. 50% or lower will yield very nice results with much less render time. |
|
|
Transfer Mode | The method to composite the effect onto the layer. When set to None, the effect is composited on black. |
Opacity | Transfer opacity of the effect. |
