# Create custom post-processing effect with Volume support
|
||
|
|
|
||
|
|
This page describes how to create a custom post-processing effect with Volume support.
|
||
|
|
|
||
|
|
URP provides a template for custom post-processing effects. The implementation in the template consists of a Renderer Feature, where you can inject the code for the custom effect, and the script that implements the code for interacting with the Volume component.
|
||
|
|
|
||
|
|
To create an effect using the template, select the following menu item:
|
||
|
|
|
||
|
|
* **Assets** > **Create** > **Rendering** > **URP Post-processing Effect (Renderer Feature with Volume)**.
|
||
|
|
|
||
|
|
Unity creates two new scripts in the `Assets` folder: the script containing the Renderer Feature template and the Volume component script.
|
||
|
|
|
||
|
|
The template contains the example effect implementation that inverts colors on the screen.
|
||
|
|
|
||
|
|
In the Renderer Feature, in the `Create` method you define the custom Material for the custom effect or the render pass that implements the effect logic.
|
||
|
|
|
||
|
|
The Renderer Feature script contains the `ScriptableRenderPass` implementation.
|
||
|
|
|
||
|
|
You set the shader properties for the custom effect in the following region in the render pass code:
|
||
|
|
|
||
|
|
```C#
|
||
|
|
#region PASS_SHARED_RENDERING_CODE
|
||
|
|
```
|
||
|
|
|
||
|
|
The render pass contains the following two regions. Unity selects the `PASS_RENDER_GRAPH_PATH` region and uses the render graph API if [Compatibility mode](../compatibility-mode.md) is disabled for the project, and uses the `PASS_NON_RENDER_GRAPH_PATH` region otherwise.
|
||
|
|
|
||
|
|
```C#
|
||
|
|
#region PASS_NON_RENDER_GRAPH_PATH
|
||
|
|
```
|
||
|
|
|
||
|
|
```C#
|
||
|
|
#region PASS_RENDER_GRAPH_PATH
|
||
|
|
```
|
||
|
|
|
||
|
|
To set the effect properties on the volume component, modify the following line in the `AddRenderPasses` method:
|
||
|
|
|
||
|
|
```C#
|
||
|
|
NewPostProcessEffectVolumeComponent myVolume = VolumeManager.instance.stack?.GetComponent<NewPostProcessEffectVolumeComponent>();
|
||
|
|
if (myVolume == null || !myVolume.IsActive())
|
||
|
|
s_SharedPropertyBlock.SetFloat("_Intensity", myVolume.intensity.value);
|
||
|
|
```
|
||
|
|
|
||
|
