Use Backdrop to modify your scene's backdrop color gradient and fog.

* Grab anywhere on the backdrop sphere to move or turn it by selecting with the trigger
* The backdrop sphere represents the sky dome (skybox) in the world.
* Change the backdrop gradient by selecting different colors.
* Change the fog intensity by adjusting the slider, and you can change the color by clicking on the fog rectangle.
* Reset your environment at any time by reloading it from the environment panel.
* Custom environments save with sketches
* Some environments already have textured sky dome. In that case, you will be prompted to turn off that custom skybox before you can modify it.

## 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.openbrush.app/user-guide/using-the-open-brush-tools-quick-tools-and-menu-panels/extras-panel/backdrop-panel.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.
