1. XR Setup

Enabling OpenXR

1. Project Settings → Plugins → Enable: OpenXR (or OpenXR Plugin depending on version)
2. Project Settings → XR → OpenXR → Enabled → true
3. Project Settings → XR → Shaders → Enabled → true (for XR shader support)
4. Rendering:
   • Use Forward+ or Mobile renderer (Compatibility also works for simpler scenes)
   • Set Project Settings → Display → Window → VSync Mode to Disabled (the XR runtime controls frame timing)
