# AR-Only Materials

Keep detailed browser materials while showing accurate colours in AR. Learn how to assign an alternative AR material in option sets and override rules.

## Why and when to set an alternative AR material

Many advanced 3D material parameters are not supported in AR.

{% hint style="info" %}
Read more about material parameters not supported by AR in [Unsupported AR Parameters](/augmented-reality/unsupported-parameters.md).
{% endhint %}

When you create complex materials like velvet, which uses Anisotropy for example, the result in the browser looks great. In AR, however, the material can appear completely different – most importantly, in a different tone.

By adding an alternative material for AR, the product admin can make a simplified material for AR. You do not have to compromise your browser-rendered model.

## How to set the alternative material

You can assign an alternative AR material in two places: the **option set** and the **override material rule**.

{% hint style="warning" %}
The alternative AR material is optional. If you leave it empty, the main 3D material will be displayed in AR.
{% endhint %}

### Option set

When you assign the material to the particular option in the option set, you can now also assign the alternative AR material.

### Override material rule

You can also assign the alternative AR material when you override the static material using the rule on the product level.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.mimeeq.com/augmented-reality/ar-only-materials.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
