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.
- Texture coordinate for lookup in the light distribution. Defaults to the normal.
- Light strength multiplier.
- 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 disk.
- Light intensity, typically plugged into the Strength input of an Emission node.
