This page provides information about the Light Rig Dome in V-Ray for Grasshopper.
Overview
This rig consists of a Dome Light source and a background texture. By default the background is not visible.
This rig is ideal for image-based lighting. Loading a spherical texture will automatically give you direct light, global illumination, and reflections based on the image.
By default, there is an HDRI map loaded in the V-Ray Light Rig Dome.
Input Parameters
Light On (Boolean) – Enables the Dome Light. Even when this option is disabled the texture remains visible in the background.
Visible (Boolean) – Enables dome texture camera visibility. When disabled the light still illuminates the scene but is not visible in the background.
Texture (Text) – Path to the Dome Light texture map. Invalid input file paths are auto-resolved as long as the files reside at the same location as the .gh project file. Spherical Panorama high-dynamic range images (hdr,exr) best fit this light source.
Intensity (Number) – Connect a component to this slot to regulate the intensity of the Dome Light. Calculated in Default (Scalar) units.
Rotation (Number) – Horizontally rotates the Dome Light.
Background Intensity (Number) – Multiplies the background texture intensity. The option only has an effect if Visible is enabled.
Output Parameters
Light Rig (Generic Data) – This rig should be connected to the V-Ray Renderer's Light Rig input slot.
