This page provides information about the V-Ray Spot Light in Grasshopper.
Overview
V-Ray Spot Light component creates a focused light, which is targeted towards an object in the scene. It can be connected to the V-Ray Render which automatically adds it to the rendered scene. If a list of input Positions is connected to this component multiple lights are generated. Multiple Target values can also be used.
The number of input positions determines the lights count.
Input Parameters
On (Boolean) – Enables or disables the light source.
Position (Point) – Determines the light source location (point position). If a list of input Positions is connected multiple lights are generated. Note: The number of input positions determines the lights count.
Target (Point) – The light Position and Target combined determine the targeted light orientation vector.
Color (Colour) – Sets the light source color.
Intensity (Number) – Specifies the light source intensity. Calculated in Default (Scalar) units.
Cone Angle (Number) – Specifies the angle of the light conde formed by the light. The value is specified in degrees.
Penumbra Angle (Number) - Specifies the angle within the light cone at which the light begins to transform from full strength to no lighting. When set to 0, there is no transition and the light produces a harsh edge. The value is specified in degrees.
Shadow Softness (Number) - Sets the shadow softness. Zero (0.0) makes the shadows perfectly sharp, larger values produce blurrier shadows.
Output Parameters
Light (Generic Data) – Light output that can be connected to Renderer component.
