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

Parameters
Intensity – Specifies the strength of the emitted light.
Solid Color – Specifies a color for the dome light.
Finite Dome – When enabled, the dome light becomes a finite half dome with ground.
Radius - Specifies the radius of the finite dome.
Height - Specifies the camera height for the projection.
Ground Blend - Controls the transition between the ground plane and the dome hemisphere. A value of 0.0 means a sharp transition, whereas a value of 1.0 means that the dome will morph into a sphere.
HDR Image – Maps the dome light with an .exr or .hrd image.
Rotate H – Specifies the rotation of the image in degrees.
Offset V – Specifies the vertical offset of the image.
HDR Image Preview – Previews the image. The arrows at the right corner allow you to rotate the image.
The HDR position indicators allow you to easily rotate the environment lighting and the background image in order to match the north direction (N) and the camera position (C) of the project.
Background
Background – You can choose between None, Custom, and Revit.
Brightness – Controls the brightness (color intensity) of the background.
Solid Color – Specifies a solid color to be used as background.
Image – Allows you to use an image file as background and makes the following parameters available:
Placement – You can choose between Spherical and Screen placement.
Rotate H and Offset V are available for the Spherical placement.
Rotate H – Specifies the rotation of the image in degrees.
Offset V – Specifies the vertical offset of the image.
Offset X, Offset Y, Scale X, and Scale Y are available for the Screen placement.
Offset X & Offset Y – Offset the image in a coordinate system manner where X is the horizontal direction and Y the vertical one .
Scale X & Scale Y – Scale the image. The lock icon locks the proportions of the image so that it is not distorted during scale.
Background Image Preview – Previews the image. The arrows at the right corner allow you to rotate the image.
