# Custom Scene Processors

FishNet's SceneManager uses Unity's methods under the hood, you can override its functionality to add or change how it functions. This can be useful when using addressables or for making custom loading screens.

To start, simply create a script that inherits from the [DefaultSceneProcessor](https://fish-networking.com/FishNet/api/api/FishNet.Managing.Scened.DefaultSceneProcessor.html), add it to your network manager object, and then in the [SceneManager](/docs/fishnet-building-blocks/components/managers/scenemanager.md) component on the network manager, assign it as the [Scene Processor](/docs/fishnet-building-blocks/components/managers/scenemanager.md#scene-processor).

You are encouraged to check out its full API [here](https://fish-networking.com/FishNet/api/api/FishNet.Managing.Scened.DefaultSceneProcessor.html).
{% endhint %}

### Addressables

You will need to make a custom scene processor if you want your game to make use of addressable networked scenes. Follow [this guide](/docs/guides/features/scene-management/custom-scene-processors/addressables.md) to learn a little more.

### Loading Screen

You can use a custom scene processor to easily hook up your loading screen into FishNet's networked scene loading. There is a complete tutorial for that [here](/docs/tutorials/simple/making-a-loading-screen.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://fish-networking.gitbook.io/docs/guides/features/scene-management/custom-scene-processors.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
