# XR Plug-in Management settings > Understand the settings you can configure with XR Plug-in Management. The **XR Plug-in Management** section of the Editor window contains the settings you can use to configure XR in your Unity project. Use this section to [Choose XR provider plug-ins](/engine/6000.3/manual/xr/configuring-project-for/configure-providers.md#enable) and [Configure settings](/engine/6000.3/manual/xr/configuring-project-for/configure-providers.md#configure-settings) for each XR platform your project targets. To open the **XR Plug-in management** section, go to **Edit** > **Project Settings** > **XR Plug-in Management**. The following sections describe the XR Plug-in Management [Settings](#settings), and how to interpret XR configuration issues using the [Project validation system](#project-validation). ## Settings reference You can use the **XR Plug-in Management** section to [Enable a provider](/engine/6000.3/manual/xr/configuring-project-for/configure-providers.md). Refer to the following image and table to understand the key regions of the section that you can use to enable XR providers: **The XR Plug-in Management section of the Project Settings.:** ![](/api/media?file=/engine/6000.3/media/images/xr-management-enable-plugin.png) The **XR Plug-in Management** settings: | **Label** | **Setting** | **Purpose** | | --------- | ------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | **Build target tabs** | A tab is shown for each platform build target installed for the current Unity Editor. You can add additional platform support modules with the Unity Hub. | | | **Initialize XR on Startup** | Whether the game or application starts in XR mode immediately. If disabled, then your application logic must initialize XR at the appropriate time. For example, your app might start with a normal desktop display and then swap to XR on demand. Refer to [Load XR plug-ins](https://docs.unity3d.com/Packages/com.unity.xr.management@4.6/manual/EndUser.html#load-xr-plug-ins) for more information. | | | **Plug-in Providers** | The list of known XR provider plug-ins. This list contains the plug-ins officially supported by Unity or its strategic partners, and any third-party provider plug-ins you have installed with the Package Manager. | | | **XR Plug-in Management menu** | Tabs to manage provider plug-in settings, and validate your project. Refer to [XR Plug-in Management menu reference](#menu) for more information. | ## XR Plug-in Management menu reference For each plug-in provider you [enable](/engine/6000.3/manual/xr/configuring-project-for/configure-providers.md#enable) in the plug-ins section , a new menu item appears in the left-hand menu, underneath **XR Plug-in Management**. You can open these provider sections to configure provider-specific settings, as described in [Provider plug-in settings](#provider-settings). **Unity adds enabled plug-ins as tabs in the left-hand menu.:** ![](/api/media?file=/engine/6000.3/media/images/xr-plugin-management-enable-plugins.png) This menu also provides options to validate your project and to configure XR simulation in your project, as outlined in the following image and table: **The XR Plug-in Management menu items.:** ![](/api/media?file=/engine/6000.3/media/images/xr-plugin-management-menu.png) | **Item** | **Description** | | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Provider plug-in settings** | The settings for each installed XR provider plug-in appear in their own pages within the **XR Plug-in Management** section. For information about the available settings for a specific plug-in, refer to that plug-in's documentation, available from [Provider plug-ins](/engine/6000.3/manual/xr/support/support-packages.md#plug-ins). | | **Project Validation** | Displays the results of project validation checks for the plug-ins you have enabled. To view the checks, select the **Project Validation** page inside the **XR Plug-in Management** section of your **Project Settings**. For more information, refer to [Project validation](#project-validation). | | **XR Simulation settings** | The AR Foundation package provides an **XR Simulation** feature, which lets you test AR Scenes in the Unity Editor. Visit [XR Simulation project settings](https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@6.3/manual/xr-simulation/simulation-project-settings.html) for a description of these settings and options. | ## Provider plug-in settings The settings that you can configure for your target platform depends on the provider plug-in. To learn about settings for a specific provider, refer to the documentation of the individual plug-in, which you can access from [XR packages](/engine/6000.3/manual/xr/support/support-packages.md). If a plug-in supports more than one build target, its settings page includes a tab so that you can configure the settings for each target independently. For example: **Oculus provider plug-in settings with the build tab highlighted.:** ![](/api/media?file=/engine/6000.3/media/images/xr-plugin-management-oculus.png) ## Project validation reference The project validation system helps you avoid common scene and project configuration issues for the XR packages you have installed. The XR packages you have installed can include rules for the validation system. The system evaluates these rules when you make a build and whenever you have the **Project Validation** section open. To open the **Project Validation** system, go to your **Project Settings** (menu: **Edit > Project Settings**) and then select **Project Validation** in the **XR Plug-in Management** menu. The project validation system checks these rules per platform build target. Some rules might examine the current scene to verify that the project settings support features used in that scene. **The Project Validation section of the XR Plug-in Management settings.:** ![](/api/media?file=/engine/6000.3/media/images/xr-project-validation.png) | **Property** | **Description** | | ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Platform tabs** | The validation checks for each platform are grouped by platform. You can select a platform tab to view the validation checks for that platform. | | **Issue list** | The list of issues found in the project when evaluating the rules. Each issue has a severity level, description, and action button. | | **Show all** | Select to display all issues, regardless of severity. Issues marked with a green check indicate validation checks that passed and don't require any action. Successful checks are only displayed when you enable **Show all**. | | **Ignore build errors** | Select to ignore build errors. This option can sometimes be useful when debugging build problems. | | **Fix all** | Click to correct all issues that have a fix available. | > **Tip:** > > If the issue has scene objects associated with it, you can click on the message to select or highlight these objects in the Unity Editor. ### Severity level The status icons to the left of an individual validation issue indicate the status and severity of the issue. | **Status** | **Description** | | ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | Validation passed because the project and scene are either set up correctly, or the rule isn't applicable. Successful checks are hidden in the project validation issue list unless you enable the **Show all** option. | | | Validation failed, but does not block building the project. You can safely ignore these if you have set up your project differently than recommended. | | | Validation failed and blocks building the project. You can't ignore these issues. You must fix them to build the project. | ### Fix and Edit buttons The **Fix** button automatically fixes the issue in your project or scene. The **Edit** button takes you to the appropriate place in the Unity Editor where you can correct the issue in your project. Both the **Fix** and **Edit** buttons provide a tooltip explaining the steps to manually correct the issue. ## Additional resources * [XR packages](/engine/6000.3/manual/xr/support/support-packages.md) * [Configure XR provider plug-ins](/engine/6000.3/manual/xr/configuring-project-for/configure-providers.md)
