Light Conversion

Loading a scene from a previous version of LightWave will automatically convert scene lights to the correct values, but if you need to manually convert a 100 % light from the old percentage scale to Lux you can do so according to the following rules:

  • Area * 3.14
  • Distant * 3.14
  • Dome * 1.57 (converted to Distant light with the appropriate angle)
  • Linear * 3.14
  • NGon * 3.14
  • Photometric no changes, but see note
  • Point * 3.14
  • Spherical * 6.28
  • Spotlight * 3.14
  • 3rd party lights * 3.14

Photometric has no changes because Photometric lights are based on the IES data they contain that should now be accurate, rather than needing tweaking

Pi (either half, full, or double) is approximately the same light output as previous LightWave versions' 100%
