In this section we'll cover the topic about Global Illumination (GI) - a key part of the photorealistic rendering process - and its related settings.

Introduction to Global Illumination

Provides initial description of the large topic about Global Illumination (GI) - a key part of the photorealistic rendering process.

GI for Exterior and Interior Scenes

Covers some good settings of V-Ray that are appropriate for rendering exterior and interior scenes.

Environment Overrides

Describes the environment overrides settings. They specify colors or texture maps to be used during GI and reflection/refraction calculations. 

Caustics
