Section

Column width 60% Sun On (Boolean) – Enables the Sun Light. Note that disabling the Sun does not disable the Sky texture and the set is still illuminated. Sun Position (Point) – Controls the point position of the Sun. Keep in mind that the Sun is always infinitely far away (it's a directional light source). The Position combined with the Target determines the Sun direction vector. If there is no target specified it is automatically placed in the world origin. Sun Target (Point) – Controls the point position of the Sun target.  Sun Intensity (Number) – Controls the intensity of the Sun light.  Sun Filter Color (Color) – Tints the automatic Sun light color. Note that Sun light color also depends on its altitude.  Ground Color (Color) – Provides a connection slot to the Ground Albedo Color.  Caustics Radius (Number) – Defines the area around the V-Ray Sun from where the photons will be shot. Caustic Subdivs (Integer) – Determines the number of caustic photons emitted from the light source. Lower values equal noisier images for less render time. Higher values produce smoother images for longer render time.   UI Text Box type info A preview of the photon emission disk is now visible in Rhino's viewport.
