v1.6.0 16 April, 2026
  • Updated the glass material with a more accurate reflection model.
  • Added additional sky instance constructors. Sky instances can now be created using one of the 16 CIE sky types, direct and diffuse values or weather data.
  • Added an additional daylight factor analysis that can calculate daylight factors using sky instances.
  • Added the ability to select which luminance components to include during sky creation. The options are only direct, only diffuse or direct and diffuse.
v1.5.0 6 February, 2026
  • Added additional constructors to the time pattern in order to increase sampling flexibility.
  • Fixed display bug with sun rig component not using the correct scale and position.

  • Fixed permissions requirement during GPU compatibility check.
  • Fixed Grasshopper display geometry not updating with plane preview size.
  • Fixed Get Clean Mesh component where changes affected upstream instances.
  • Replaced sky component analysis with existing daylight factor analysis.
v1.3.0 18 September, 2025
  • Added ground plane reflectance to daylight and radiation analyses, specified through the sky series and sky instance.
v1.2.0 2 July, 2025
