Setting Up Build Settings for Target Platforms in Unity XR
Successfully deploying your Extended Reality (XR) application from Unity requires careful configuration of build settings tailored to your target platform. This process ensures compatibility, performance, and access to platform-specific features. We'll explore the key steps and considerations for setting up these crucial build settings.
Understanding the Build Settings Window
The heart of platform-specific deployment lies within Unity's "Build Settings" window. Access this by navigating to <b>File > Build Settings...</b>. Here, you'll see a list of available platforms and the option to switch between them. Each platform has its own set of configurable options.
Switching platforms is a fundamental step for targeting different XR devices.
Before building, you must select your desired target platform from the 'Build Settings' window. This action tells Unity to prepare your project for that specific environment, adjusting settings and compiling appropriate code.
Unity supports a wide array of XR platforms, including Android (for Oculus Quest, Pico, etc.), iOS (for ARKit-enabled devices), Windows (for PC VR like SteamVR, Oculus Rift), and more. Selecting a platform here not only changes the build output but also influences which Unity packages and settings are active, ensuring your project is optimized for the chosen hardware and software ecosystem.
Key Platform-Specific Settings
Once a platform is selected, the 'Player Settings' button (accessible from the Build Settings window) reveals a wealth of platform-specific configurations. These settings are critical for performance, feature integration, and compliance with platform guidelines.
| Setting Category | Android (Quest/Pico) | iOS (ARKit) | Windows (PC VR) |
|---|---|---|---|
| <b>Company Name</b> | Your company name | Your company name | Your company name |
| <b>Product Name</b> | Your app's name | Your app's name | Your app's name |
| <b>Target SDK</b> | Android SDK Version, NDK Version | Minimum iOS Version | Target Graphics API (DirectX 11/12) |
| <b>Graphics APIs</b> | Vulkan, OpenGLES3 | Metal | DirectX 11, DirectX 12 |
| <b>XR Plugin Management</b> | Oculus, OpenXR | ARKit | OpenXR, Oculus XR Plugin |
| <b>Scripting Backend</b> | IL2CPP | IL2CPP | IL2CPP |
XR Plugin Management
Unity's XR Plugin Management system is the modern, unified way to handle XR integration. It allows you to enable and configure specific XR SDKs for your chosen platform. This is essential for your application to communicate with the target XR hardware.

Graphics APIs and Performance
The choice of Graphics API (e.g., Vulkan, Metal, DirectX) significantly impacts performance and compatibility. For mobile XR devices like the Quest, Vulkan is often preferred for its lower overhead. For PC VR, DirectX is standard. Ensure you select the appropriate API for your target platform in the Player Settings.
The Graphics API selection in Unity's Player Settings dictates how your application's visual data is translated into instructions for the GPU. For instance, Vulkan is a low-overhead, cross-platform 3D graphics and compute API. Metal is Apple's low-overhead graphics and compute API for iOS and macOS. DirectX is Microsoft's suite of graphics APIs for Windows. Choosing the correct API ensures optimal rendering performance and compatibility with the target hardware's graphics drivers.

Scripting Backend and Architecture
For most XR development, the IL2CPP (Intermediate Language To C++) scripting backend is recommended. IL2CPP converts your C# code into C++ code, which is then compiled into native machine code for the target platform. This generally results in better performance and compatibility, especially on mobile and console platforms.
Always ensure your project's architecture (e.g., ARM64 for modern mobile devices) aligns with the target platform's requirements.
Build and Run
After configuring all necessary settings, you can initiate the build process by clicking the 'Build' button in the Build Settings window. Unity will then compile your project into an executable file or package suitable for your chosen platform. You can also use 'Build And Run' to automatically deploy the application to a connected device.
