MRTK 3 Magic Leap Quick Start

The fastest way to get started with MRTK3 on Magic Leap 2 is to use the Magic Leap MRTK3 Template Project. The Template project is pre-configured for Magic Leap and contains all of the required MRTK3 and Magic Leap packages in addition to some sample scenes. This guide includes step-by-step instructions on how to download the Magic Leap 2 MRTK Template Project.

Prerequisites​

Before starting, download and install the following packages from the Magic Leap Hub:

  • Magic Leap SDK v1.2.0 (or later)
  • Magic Leap Unity SDK v1.8.0 (or later)
  • Unity Editor v2022.2.17f1 (or later)
note

If updating to Magic Leap Unity SDK 1.10.0 or 1.11.0, there may be a compile issue if your project contains the Unity OpenXR package. A workaround for this is to remove the OpenXR package from the project in this situation.
