This page provides information on the V-Ray Light Rectangle Blueprint.


 

 

 

Overview


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.
