Stereo rendering

VR and most MR devices require rendering the Unity scene in stereo. Unity XR supports two stereo render modes:

• Multi-pass: in this mode, Unity renders the scene twice, performing a pass for each eye. This mode provides the widest compatibility with existing shaders and rendering utilities, but is the slower of the two modes.
• Single pass instanced: in this mode, Unity renders the scene in a single pass using instanced draw calls. This mode greatly decreases CPU usage and slightly decreases GPU usage compared to rendering the scene twice.

Note: The earlier technique of rendering the scene into a double-wide texture using a single render pass is no longer available.

Set the render mode

You can find the Render mode setting under XR Plug-in Management in Player Settings. Each XR provider plug-in provides its own setting, if it supports different render modes.

To set a render mode:

1. Open Project Settings (menu: Edit > Project Settings).

2. Expand the XR Plugin Management section, if necessary.

3. Select the settings page for the relevant provider plug-in.

4. Choose a mode from the list.

Note: Some plug-ins name the setting Stereo Rendering Mode.
