The V-Ray Light Mesh is a V-Ray specific light source plugin that can be used to create light sources that have volume and shape without the need to use self-illuminated objects and global illumination. |

This page provides information about the Light Mesh in V-Ray for Grasshopper.

On (Boolean) – Enables or disables the light source.
Texture (Text) – Specifies the color or the texture of the light. A high dynamic range texture can be used.
Intensity (Number ) – Light source intensity. Calculated in the specified units.
Intensity Units (Integer) – Specifies the light unit of measurement. Using correct units is essential when working with physical camera exposure. The light automatically takes the scene units scale into consideration to produce correct result for the scale being worked in.
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. 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.
Invisible (Boolean) – Controls the light source visibility. It does not affect its illuminance.
Geometry (Generic Data) – Geometries input is expected in this slot.
Add Light (Generic Data) – Light output that can be connected to a V-Ray Render component.
