# 3. Fluid Controller

## Setting up the Fluid Controller to your scene

Navigate to your *Place Actors* tab and search for "Fluid Controller". Select the **BP\_FluidController** from the list and place it within your scene.

Once placed in the scene, navigate to the *Details Panel*.

Under the *Render Targets* category, make sure your previously created Render Targets are input into the **Fluid Out** parameters.

{% hint style="info" %}
You will need to add multiple Fluid Controllers and add the correct **Fluid Out** Render Targets if you plan to have multiple fluid simulations.
{% endhint %}

You can also change some of the fluid simulation settings in this *Details Panel*.

* **Fluid Update Rate**: This will change the rate at which the fluid simulation ticks.
* **Fluid Travel Speed**: This will change the speed at which the fluid ripples travel.
* **Fluid Dampening**: This changes the dampening amount for the fluid ripples.
* **Normal Intensity**: This changes the overall normal calculation intensity for this fluid simulation.

## 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://docs.shadersource.io/assets-and-plugins/fluid-interaction-tool/how-to-use/3.-fluid-controller.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.
