In this section we'll cover thoroughly (almost) all light types available in V-Ray: Light RectangleV-Ray Rectangle Light is a planar light source with the shape of a rectangle or of a circular disk. Rectangle lights are useful for simulating man-made light sources, such as lamps, in an interior environment. Light OmniV-Ray Omni Light is a V-Ray specific light that can be used to create physically accurate lights. It casts rays in all directions from a single source. Directional LightThe V-Ray Directional Light is a V-Ray specific light source plugin that can be used to create physically accurate area lights. Spot LightV-Ray Spot Light is a V-Ray specific light source plugin. Use it to create a physically accurate light that directs a narrow beam of light with falloff. Dome LightDome light (also known as Area light) creates light within a dome or spherical shape to create a traditional global illumination setup. This light is frequently used to load HDRI environment images. Sphere LightSphere Light is a V-Ray Light object in the shape of a sphere, casting light outward in all directions. Mesh LightMesh Light can create light sources that have volume and shape defined by geometry in the scene without the need to use self illuminated objects and global illumination. IES LightIES lights are designed to realistically simulate the distribution pattern of a light source by loading and using an IES (Illumination Engineering Society) file. An IES profile contains details about the behavior of the light, such as how the light passes through fresnel lenses, its intensity, and its falloff. Sun SkyPhysically-based model of a Sun directional light source. Positioned at infinity and casts parallel rays with soft shadows.
