IES Texture Node
The IES Texture is used to match real world lights based on IES files (IES). IES files store the directional intensity distribution of light sources.
Texture coordinate for lookup in the light distribution. Defaults to the normal.
Light strength multiplier.
The location to load the IES file from.
Use IES profile from a file embedded in a text data-block in the blend-file, for easy distribution.
Load IES profile from a file on the drive.
Light intensity, typically plugged into the Strength input of an Emission node.
