Depth API Samples

Updated: Apr 14, 2026
The Depth API enables virtual objects to be occluded by real-world surfaces, creating more believable mixed reality experiences. The following sample projects demonstrate Depth API features in Unreal Engine. These samples require a Meta Quest 3 or Meta Quest 3S with Passthrough enabled.

Occlusion Sample

Occlusion Sample on GitHub⁠
This Blueprint-only project demonstrates several Depth API features:
  • Hard occlusions: Real-world surfaces occlude virtual objects with sharp edges.
  • Soft occlusions: Real-world surfaces occlude virtual objects with smooth gradient edges. Requires the Oculus-VR fork of Unreal Engine.
  • Hands removal: Toggles hand removal so that the user’s hands are not occluded by virtual content. Activated with a pinch gesture.
  • Environment Depth material graph node: Visualizes raw depth data from 0 to 3 meters using a custom material (M_EnvironmentDepth). Requires the Oculus-VR fork of Unreal Engine.
Use the A/X buttons to cycle between occlusion modes.

Phanto

Phanto on GitHub⁠
Phanto is a mixed reality game that integrates Passthrough, Depth API occlusion, and Scene Mesh into gameplay. It demonstrates how depth-based occlusion and scene understanding can combine to create interactive mixed reality experiences where virtual content responds to the physical environment.
  • Passthrough integration: Renders the physical environment as the backdrop for mixed reality visuals.
  • Depth API occlusion: Integrates depth-based occlusion into gameplay mechanics so virtual content is hidden behind real-world surfaces.
  • Scene Mesh interaction: Uses the scene mesh to enable virtual content to interact with the physical environment.
