Version 77.0 Release Notes

What's Fixed

  • Added ControllerTouchHandGrab component to UnityXRComprehensiveRigExample scene.
  • Added ground detection to FirstPersonLocomotor to prevent automatic falling.
  • Fixed teleport arc collision with TransparentFX layer by updating layer mask.

    • Improvements

  • Improved locomotion safety with configurable ground checks and warning logs.
  • Enhanced HandGrabPose mirroring with platform-specific rotation offsets (OpenXR/OVR).

    • Known Issues

  • There is a Unity bug that causes APK crashes in scenes that contain both a video player and skinned mesh renderer. This crash happens when using OpenGLES, and ISDK users may encounter this in our sample scenes depending on project configuration. To work around this problem, you can either disable “GPU Compute Skinning” in player settings, or set your project’s Graphics API to Vulkan.
  • When using ISDK with an XROrigin camera rig, such as in the UnityXRComprehensiveRigExample scene, be sure to apply the XR Project Validation fix “Switch to use InputSystem.XR.PoseControl instead of OpenXR.Input.PoseControl” in player settings, otherwise controller tracking will fail.
