This page gives information about the Lighting Render Element.
Overview
The Lighting Render Element stores direct lighting information from lights in the scene, and materials as lit by the lighting. This render element can be used to brighten, lessen, or tint the direct lighting in a composite.
The VRayLighting render element is the same as VRayRawLighting multiplied by VrayDiffuseFilter. VRayLighting is provided as a convenience to the compositor.
Since V-Ray Next Update 1, some of the render elements are rendered differently than before. The Lighting render element now contains all direct diffuse illumination and the GI element contains all indirect diffuse illumination. Similarly, all direct reflections of lights now go to the Specular element and all indirect reflections go to the Reflection element.
Parameters
This render element is enabled through the Render Elements tab of the Render Setup window in 3ds Max and displays its parameters in a rollout at the bottom of the window:
VrayVFB – When enabled, the render element appears in the V-Ray Virtual Frame Buffer.
Deep output – Specifies whether to include this render element in deep images.
Color mapping – Applies the color mapping options specified in the Color mapping rollout of the V-Ray tab in the Render Setup window to this render element. This option is enabled by default.
Multiplier – Sets the overall intensity of the render element, where 1.0 is the standard multiplier.
Denoise – Specifies whether to denoise this render element.
Common Uses
The Lighting Render Element is useful for changing the appearance of direct illumination after rendering in a compositing or image editing application. Below are a couple of examples of possible uses.
