Our new XR e-book is here: Build XR with Unity: Meta XR

Unity has published an e-book titled Build XR with Unity: Meta XR, aimed at developers using Unity XR to create new titles or port existing apps to Meta VR devices. The guide covers practical workflows, including setting up a VR template in Unity Hub with sample scenes and recommended packages. It specifies Unity 6.6 and XR Interaction Toolkit 3.6 as the baseline versions for compatibility and portability across platforms.

The e-book details device setup steps, such as enabling Developer mode on Meta Quest devices and configuring build profiles to target Meta Quest. It highlights the use of the XR Interaction Simulator for testing interactions within the Unity Editor and Meta Horizon Link for Windows users to streamline deployment without repeated builds.

For Meta VR Glasses specifically, the guide explains how to leverage increased on-chip GPU memory by adjusting foveated rendering approaches when porting projects from Quest 2 or Quest 3. It emphasizes benchmarking to determine optimal performance settings for the new hardware.

The e-book also introduces Unity’s new CLI and Pipeline package, enabling command-line control of the Unity Editor for faster automation and AI-assisted workflows. It includes experimental Meta XR Operator for agent-driven testing inside running XR apps, with instructions to prioritize physical hardware testing for comfort and performance validation.
