# Emission Node
|
|
|
|
The Emission Node allows you to apply emission in your Shader Graph.
|
|
|
|
## Render pipeline compatibility
|
|
|
|
| **Node** | **Universal Render Pipeline (URP)** | **High Definition Render Pipeline (HDRP)** |
|
|
| -------- | ----------------------------------- | ------------------------------------------ |
|
|
| Emission | No | Yes |
|

|
|
| **color** | Input | LDR Color(RGB) | Sets the low dynamic range (LDR) color of the emission. |
|
|
| **intensity** | Input | Float | Sets the intensity of the emission color. |
|
|
| **output** | Output | HDR Color(RGB) | Outputs the high dynamic range (HDR) color that this Node produces. |

## Notes
|
|
|
|
### Emission Unit
|
|
|
|
You can use two [physical light units](https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@latest/index.html?subfolder=/manual/Physical-Light-Units.html) to control the strength of the emission:
|
|
|
|
* [Nits](https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@latest/index.html?subfolder=/manual/Physical-Light-Units.html%23Nits).
|
|
* [EV<sub>100</sub>](https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@latest/index.html?subfolder=/manual/Physical-Light-Units.html%23EV).
|
|
|
|
|
|
### Exposure Weight
|
|
You can use Exposure Weight to determine how exposure affects emission. It is a value between **0** and **1** where. A value of **0** means that exposure does not effect this part of the emission. A value of **1** means that exposure fully affects this part of the emission.
