IES Texture Node
![../../../_images/render_shader-nodes_textures_ies_node.png](../../../_images/render_shader-nodes_textures_ies_node.png)
Gradient 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.
Examples
