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.

Inputs

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

Properties

Mode

The location to load the IES file from.

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 the drive.

Outputs

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