# Viewer Settings

## Environments

Switch between various environments to change the background and lighting of the model. The default environment is set to 'Neutral' for a balanced and unobtrusive appearance. Additionally, you can upload your own custom environment to personalize the scene further.

## Exposure

Adjust the model's exposure to control its brightness, with a range from 0 (darkest) to 2 (brightest). The default exposure is set to 1 for balanced lighting.

## Dimension Ruler

Activate the dimension ruler to turn the dimension feature dynamiclly on and off. Measurements are displayed based on the viewer's location, either in centimeters or inches. You can also configure the dimension feature to start enabled, ensuring that the model is displayed with dimensions turned on by default.

## Auto Rotate

Enable the auto-rotate feature to showcase the model with continuous rotation. Choose from left or right rotation to set the direction, or switch it off for a static view.

## Create Poster

Capture a poster of the model to serve as a preview image while the model is loading. The poster also sets the starting position of the model, ensuring a consistent initial view when loaded.

## Tone mapping

Choose between different tone mapping options to control how colors and brightness are displayed in the model. Customize the visual style to suit your preferences or match the desired aesthetic.

## 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://mazingxr.gitbook.io/mazing-world/product-guides/premium-features/viewer-settings.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.
