Meta XR Interaction SDK Unreal

Download
Updated: Apr 15, 2026|
Version
201.0
The Meta XR Interaction SDK package contains an Unreal plugin that can be used to build rich UI and 3D object interactions.

Version 201.0 Release Notes

The Meta XR Interaction SDK for Unreal Engine makes it easy for VR users to immersively interact with their virtual environment. With Interaction SDK, you can grab and scale objects, push buttons, navigate user interfaces, and more while using controllers or just your physical hands.

More information is available in our documentation.

A sample project is available on github.

What's New


By default, a grabbed object is released when the user opens their hand or releases the grab gesture. Grab stickiness uses the bIsStickyproperty on IsdkGrabbable to override this behavior so the object remains attached to the hand until it is explicitly released by calling the ReleaseStickyGrabbable() method on the IsdkGrabber that is holding the object. This is useful for objects that should stay locked to the user's hand, such as tools, weapons, or attachments.

What's Fixed

  • Improved API documentation across the SDK.
  • Made optimizations is many areas to increase performance and efficiency.
  • DistanceGrabDetector no longer ticks when Distance Grab is disabled.
  • Attachment of subobjects has been deferred to BeginPlay for RoundedButton, RayVisualComponent, GrabbableMeshComponent

    • Known Issues

  • It may be possible to grab a stuck object with the other hand. A hotfix will be deployed. Until then, this can be fixed locally in IsdkGrabberComponent.cpp, line 647, add:


    • if (NumGrabbers >= 1 && GrabCandidate->IsSticky())
{
  return;
}
