Version

205.0

The Meta XR Interaction SDK package contains an Unreal plugin that can be used to build rich UI and 3D object interactions.

Version 205.0 Release Notes

What's New
Linux is now a supported target platform for Unreal Interaction SDK
Hand visuals now scale to match the size of the user's actual hands on the OVRPlugin code path.
Switching between hands and controllers now keys off the active OpenXR interaction profile. This resolves the "hand frozen in mid-air" issue during transitions and improves reliability when only one controller is connected
What's Fixed
Interaction & Physics
Fixed gravity being inverted on release when throwing an object configured not to retain gravity
Fixed equality comparison for hand grab pose properties
Fixed the ray visualizer not appearing on freshly created controller/hand rig Blueprints
Fixed physics state being applied to the wrong mesh on rounded button components
Editor Tooling
Restored Hand Grab Pose gizmo functionality in the Editor for Unreal Engine 5.6+, so bone rotations can be authored correctly again
Debug Visualization & Diagnostics
Fixed an inverted guard that caused poke interaction debug visuals to render only when they were meant to be disabled
Fixed ray grab debug lines to use the intended thickness and corrected handedness mismatch log warnings
Correctness & Asset Validation
Fixed validation of the one-sided transparent widget material and dependency validation in the poke limiter visual
Stability & Crashes
Fixed a crash on Editor startup in DebugGameEditor configurations caused by the engine telemetry library being loaded twice when the MetaXR plugin is present.
Fixed a null-dereference crash (drawing debug visuals) and potential division-by-zero (velocity estimation)
Improvements
Optimized several per-frame hot paths (grabber visuals, grab collider lookups, and hand bone-chain traversal) and disabled ticking on idle sample actors, alongside Unreal Engine 5.7 compatibility updates, cleanup of uninitialized-property warnings, and expanded automated unit test coverage
Known Issues
There is a known Vulkan-related crash when using an APK packaged as a Shipping build using the MetaXR plugin and the ISDK Samples project. We are working to fully identify the problem areas and hope to provide engine-level fixes when able.

Supported Unreal Engine versions
Unreal Engine 5.8
