This page provides information on the V-Ray Dome Light.
Overview
V-Ray Dome Light shines inward at the scene as if from a spherical or hemispherical light source outside the scene extents. This light is frequently used for Image-Based lighting using panoramic HDR images as environments.

Parameters
Options
Example: Background
This example shows how the render changes according to the visibility of the Dome light and the map attached as a Color/Texture.
Example: Shape of Dome Light
The example below shows the difference between the two types of Dome Light - a sphere or a hemisphere. When a sphere is used the projection of the HDRI goes below the horizon, while when a hemisphere is selected, the render is halved in two by the horizon.
Example: Placing objects into HDRIs using finite dome light
Notes
- Left-clicking the Dome Light V-Ray toolbar button leads to creating a Dome light at a specified point, and right-clicking – as a spherical dome light. These options are also available in the vrayLightDome command.
- When using V-Ray GPU, the Texture Resolution parameter also affects the background resolution.
