Inputs

  • input : RGB encodes XYZ normals from -1 to 1. Uses world-space directions with +Y up.

Parameters

ParameterTypeDefaultRangeDescription
horizontal_angle
Horizontal Angle		float0.250 to 1Direction in turns around +Y: 0 faces -X, 0.25 faces +Z, 0.5 faces +X, and 0.75 faces -Z.
vertical_angle
Vertical Angle		float0.1250 to 1Elevation in turns: 0 is the XZ plane, 0.25 points up (+Y), and 0.75 points down (-Y).
highlight_glossiness
Highlight Glossiness		float0.50 to 0.999Sets the lower threshold of the directional response. 0.5 gives diffuse lighting; higher values isolate tighter highlights.
highlight_level
Highlight Level		float00 to 1Moves the white threshold toward the glossiness threshold. 0 gives the full falloff; 1 gives a hard threshold.
