Parameter Description
Intensity Determines the amount of diffuse light on the image.
Increase this value to enlarge the size of the lit region and make the center
of the lit area increasingly bright.
Specular Determines the amount of specular light applied to the image.
Increase this value to raise the amount of light at the center of the lit region
(determined by the Light X, Y, and Position settings).
Specular
Falloff
Controls the relative softness of the edges of the region lit by specular
light.
Increase this value to soften the edges of this region and decrease its size.
Parameter Description
Target X
Target Y
Sets the X and Y coordinates for the point at which the spotlight is aimed.
Changing the Target point is analogous to pivoting a theatrical spotlight to
follow a performer on stage.
Cone Width Adjusts the size of the light cone.
• Increase this value to enlarge the size of the cone base.
• Decrease this value to reduce the size of the lit region.
Unlike a physical spotlight changing the cone width of the light does not
affect its intensity.
Intensity Controls the brightness of the spotlight.
Unlike the Diffuse Specular Intensity parameter, changing Spotlight
Intensity does not affect the size of the lit area.
