This page gives an overview of the Lighting render elements that may be generated through V-Ray and how they are used in compositing.

V-Ray Lighting Render Elements are a group of elements that store lighting information from the scene. Each element can be individually adjusted during the compositing phase to change the look of the render as desired without the need for re-rendering the scene. The following lighting render elements are supported by V-Ray for Modo:

  • Ambient Occlusion – Generates an image where occluded areas such as those in crevices and corners have a darker color. Areas that are in the open and could feasibly be hit by light will render as a lighter color (approximating a Global Illumination type of shading).
  • Raw Lighting – Outputs all illumination for the scene that comes from all direct lights, area lights, point lights spot lights and distant lights. It is independent of all other illumination and surfacing types.
  • Raw GI – Renders an image of all indirect illumination in the scene. Dome lights, image based lighting and all objects that have luminous materials are taken into account. The render element presents the raw diffuse global illumination (not multiplied by the diffuse surface color) and is only relevant when Global Illumination is enabled. Otherwise, its output is black.
  • Raw Total Light – Outputs the raw diffuse direct illumination of the scene before it is multiplied by the diffuse surface color. This render element contains the full illumination of the scene, including direct and indirect raw lights as well as all shadows cast by any direct light sources.
  • Reflection Occlusion – Renders a black and white image by determining if a reflection ray of an object has hit any other geometry in the scene. The white areas denote where the reflection ray would hit an object. The render element is black in other areas.
  • Matte Shadow – Renders an image generated from the density of all the shadows cast by direct light, excluding color shading or textures. The darkest areas of the shadows will render as white, gradating towards black for the areas that are fully illuminated. Non-grey colors may be produced depending on light color and occluded/unoccluded matte surfaces.
