****************
IES Texture Node
****************

The *IES Texture* is used to match real world lights based on IES files.
IES files store the directional intensity distribution of light sources.


Inputs
======

Vector
   Texture coordinate for lookup in the light distribution.
   Defaults to the normal.
Strength
   Light strength multiplier.


Properties
==========

Mode
   Internal
      Use IES profile from a file embedded in a text data-block in the blend-file, for easy distribution.
   External
      Load IES profile from a file on disk.

Outputs
=======

Factor
   Light intensity, typically plugged into the Strength input of an Emission node.


Examples
========
