Overview of Weblights
Weblights are photometric lights with customized, real-world light
distributions.
A weblight (web) is a 3D representation of the light intensity distribution of
a light source. Weblights can be used to represent anisotropic (non-uniform)
light distributions derived from data provided by manufacturers of real-world
lights. This gives a far more precise representation of the rendered light than
either spot or point lights are capable of.
This directional light distribution information is stored in a photometric data
file in the IES format using the IES LM-63-1991 standard file format for
photometric data. You can load photometric data files provided by various
