This page gives an overview of the Render Elements available in V-Ray that contain lighting information.

Overview

V-Ray Lighting Render Elements provide a comprehensive set of individual channels, each containing a separate component of lighting from the scene. Each element can be individually adjusted during the compositing phase, to change the Beauty pass as desired without the need for re-rendering. 

The Lighting Render Elements are:

  • Lighting - Stores direct lighting information from lights in the scene, including the diffuse contribution.
  • Light Select - Stores direct lighting information from user-selected lights in the scene; can also be limited to the light's raw, diffuse, or specular contribution.
  • Raw Lighting (Light Raw) - Stores the effects of direct lighting on scene objects without the diffuse contribution.
  • Total Lighting (Light Total) - Stores the effects of both direct and indirect lighting on materials in the scene, including the diffuse contribution.
  • Raw Total Lighting (Light Raw Total) - Stores the sum of both direct and indirect lighting in the scene without the diffuse contribution.

Notes

  • Lighting can be be added or subtracted at a composite level using Lighting Render Elements.

  • Lighting can be color corrected.

  • When using the light select render element, lights can effectively be turned on and off at a composite level without re-rendering.
