📄️ Overview
The transition to OpenXR involves the phasing out of MLSDK in favor of OpenXR extensions. To align with this change, Magic Leap’s Unity SDK is shifting from Unity's platform specific XR Plugin (ie: com.unity.xr.magicleap) to Unity's OpenXR Plugin (com.unity.xr.openxr). This shift is accompanied by the addition of new OpenXR Features and API for accessing the functions previously defined by MLSDK C-APIs. This document will outline the rationale behind the move to OpenXR, detail the steps involved in the migration process, and provide insights into the changes and enhancements introduced by this transition.

📄️ Mixed Reality Capture Tips
This document includes tips on ensuring proper composition of virtual and reality world content when using mixed reality capture.
📄️ MRTK Compatibility
Use the following chart to see if your project is compatible with MRTK 2.8 or MRTK 3.0.
📄️ Near Clip Policy
In order for virtual content to be rendered comfortably, Magic Leap 2 enforces a minimum clipping plane. By default this value is .37 meters or 37 centimeters but can be adjusted by the user inside the device settings (Settings > Display > Advanced > Display Zone) based on their comfort preferences, up to a minimum of 25 centimeters. Applications can choose if they want to use the near clipping plane distance set by the user or if it should remain at the default minimum value. If the Camera's Near Clip Plane value is set to lower than the enforced range it will be reverted to the enforced value.

📄️ Reprojection
The Magic Leap 2 Reprojection feature enables an application to provide additional reprojection information for a projection composition layer to help virtual content appear more stable and improve visual quality. This is an advanced feature that can be used as an alternative instead of the the existing FocusDistance, and requires some experimentation. When the Magic Leap 2 Reprojection feature is enabled, the focus distance is no longer used.
📄️ Secondary View
The Magic Leap 2 Secondary View feature leverages the OpenXR XRMSFTfirstpersonobserver extension to enhance Mixed Reality capture. By rendering a secondary view from the RGB camera's position, it ensures precise alignment of physical and virtual content. This feature addresses common issues in mixed reality (MR) capture, improving overall quality.
📄️ IMU Sensors
Sensors are devices that measure environmental characteristics of the device that the content is running on, such as light, pressure, temperature, orientation, and motion. Unity’s Input System allows you to access sensors on Android devices using the standard Android Sensor API. In this guide, we will show you how to enable, disable, and read data from sensors on Android using the Input System.
