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.
