Enabled () – Turns the V-Ray Dome Light on and off.
Color/Texture HDR – Specifies the color of the light. A high dynamic range texture can be used. Make sure that the map checkbox is enabled for the texture to take effect.

info
A bitmap image (HDRI) connected to the Dome Light automatically uses a UVWGenEnvironment Spherical Mapping Type placement. The rotation of the image can be adjusted from the Bitmap UVW options using the Vertical and Horizontal rotation parameters. For more information, see the Bitmap page.
Intensity– Specifies the strength of the light.
Units – Specifies the light unit of measurement. The light automatically takes the scene units scale into consideration to produce а correct result. Using correct units is essential for working with physical camera exposure.
Default (Scalar) – The color and multiplier directly determine the visible color of the light without any conversion. The light surface appears with the given color in the final image when seen directly by the camera. Luminous Power (Lumens) – Total emitted visible light power measured in lumens. The intensity of the light does not depend on its size. A typical 100W incandescent light bulb emits about 1500 lumens of light. Luminance (lm/m^2/sr) – Visible light surface power measured in lumens per square meter per steradian. The intensity of the light depends on its size. Radiant Power (W) – Total emitted visible light power measured in watts. The intensity of the light does not depend on its size. This is not the same as the electric power consumed by a light bulb for example. A typical 100W light bulb only emits between 2 and 3 watts as visible light. Radiance (W/m^2/sr) – Visible light surface power measured in watts per square meter per steradian. The intensity of the light depends on its size.
Shape – Controls whether the Dome light covers the entire scene or only half above the horizon. See the Shape of Dome Light example below for illustration.
Finite Dome – Enables the finite dome projection mode. If enabled, the dome light becomes a finite half dome with ground. See the Embed models in HDRIs with the finite dome mode example below.
Radius – Specifies the radius of the projection.
Projection Height – Specifies the camera height for the projection.
Ground blend – Specifies the blending amount between the finite ground and upper hemisphere.
Use Transform – When enabled, the HDRI texture locks to the orientation of the V-Ray Dome widget and allows them to rotate together in the scene.
Adaptive – Enables the Adaptive Dome Light sampling method. Note that Light Cache has to be selected as a secondary GI engine in order for this optimization to work. This limitation does not apply to the V-Ray GPU engine.

When using V-Ray GPU, the Texture Resolution parameter also affects the background resolution.
Scene units in SketchUp are always calculated in inches.
