This page gives some basic details about the Raw Total Lighting Render Element and explains how it is used in compositing.

Overview  

UI Path

||Render Setup window|| > Render Elements  tab > Add button > VRayRawTotalLighting

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 Raw Total Lighting Render Element is useful for changing the appearance of the entire lighting of the scene after rendering, using a compositing or image editing application. Below are a couple of examples of possible uses. The first two images show the render element itself and the Beauty render put together. In the following examples, a Matte Render Element was used to isolate different parts of the scene, and then the Raw Total Lighting Render Element was brightened and tinted differently to show the range of editing possible.

Underlying Compositing Equation

VRayRawTotalLighting x VRayDiffuseFilter = VRayTotalLighting

VRayRawLighting + VRayRawGlobalIllumination = VRayRawTotalLighting
