This page provides information on the V-Ray Light Rectangle Blueprint.
|The V-Ray Light Rectangle, or area light, is a planar light source with the shape of a rectangle or a circular disc. Rectangle lights are useful for simulating man-made light sources in an interior environment, such as lamps. A rectangle light can one of two possible shapes: plane or disc.|

Enable – When enabled (the default), the light contributes to the lighting in the level. Disabling it will stop the contribution of the light in the environment.
Is Disc – The VRayLight takes the shape of a planar disc.
Length/ Radius – The length of a Plane light source/radius of the Disc light source, measured in scene units.
Width – The width of the Plane light source, measured in scene units.
Multiplier – Specifies the intensity multiplier in lumens of the rectangle light.
Cast Shadows – When enabled (the default), the light casts shadows. Turn this option off to disable shadow casting for the light.
Color – The color that the light emits.
Invisible – Controls whether the shape of the light source is visible in the rendered image. When this option is disabled, the light source is rendered in the color specified by the Color setting. This option only affects the visibility of the light when seen directly by the camera or through refractions.
Enable After Light Bake – Enable this option only after you have done a light bake in the level.
