What's New

  • Meta Horizon Link now supports Passthrough Camera Access API (PCA).
  • We're standardizing our OS versioning to provide more clarity on the scope and impact of each release. This helps you plan your development by making critical updates predictable and support documentation easier to navigate. Going forward, you'll see this new versioning system (e.g., OS 200, 201).

    • What's Fixed

  • Fixed a null pointer exception on shutdown in EnvironmentRaycastManager.
  • Destructible mesh uses standard shader by default.

    • Known Issues

  • Stage tracking over Meta Horizon Link is not working. We recommend using Floor Level as an alternative until a fix is available in the next release.
