The plug-in translates Houdini’s hlight node to Maxwell Render with creating the appropriate geometry and applying an emitter material to it. The valuable used parameters are summarized in the following tabletables:

Houdini hlight nodeMaxwell light geometry
Type: pointSphere with radius of 0.05

Light Intensity

Normalize Light Intensity To Area

Intensity translated linearly in the following intervals:

[0 ; 0.1] -> [0 ; 10^4]

[0.1 ; 1] -> [10^4 ; 10^5]

[1 ; 10] -> [10^5 ; 10^7]

Set as Luminous Intensity (Candela) for:

  • point or line type
  • rectangle or disk type when Normalize Light Intensity To Area is turned on

Set as Luminance for:

  • sphere or geometry type
  • rectangle or disk type when Normalize Light Intensity To Area is turned off
