Motion Controller Key Deprecation
Motion Controller keys have been deprecated in 4.24 in favor of keys specific to a set of common XR controllers which are defined in the OpenXR specification. This change makes it easier to customize the input bindings for each controller model and gets rid of the ambiguity around the mapping of Motion Controller keys to physical controller buttons.
By using the new keys, projects will improve support for SteamVR Input and OpenXR which are built around action systems. These new XR input systems are designed around providing cross-device compatibility by emulating the specific controller that the project is targeting.
During the deprecation existing inputs using Motion Controller keys are still supported, however it’s no longer possible to add new inputs using Motion Controller keys. Any new input has to use the new XR keys, however the upgrade of old inputs can be done piecemeal since it’s possible to use both the old and new keys interchangeably.
