Nativization isn’t officially supported in Unreal Engine 5, but for folks in Unreal Engine 4, it may still be beneficial to keep it enabled depending on your project’s needs. This is because the Oculus Hand Component is a part of the OculusVR plugin, which is only enabled for Windows and Android and therefore can’t have any of its components referenced in Blueprints when other platforms are built. The Oculus Hand Component being serialized with any Blueprint will cause builds for other platforms (such as Xbox) to break during the nativization step. We fixed this by changing the event in the Oculus Input library to wait for the pinch to complete (wait for the system gesture to fill in its confirmation circle) before firing off a notify event instead of doing so while it’s in progress. The Oculus left-hand system gesture (this is for the menu button) will trigger even if you begin a pinch, instead of waiting to confirm the pinch has been in the same state for a period of time. Much of Meta’s gesture detection and physicality libraries for hand tracking are only available in Unity at this time, so we needed to do some ground work on that front to get simple gestures like our ‘thumbs-up’ and ‘finger pointing’ gestures recognized in Unreal.Īdditionally, there are some other elements folks will need to implement themselves for a shippable hand tracking project, which I’ll detail below. Meta has some base code for hand tracking in Unreal-but not enough for a game like ours that requires better gesture and confidence detection. We’re currently using Unreal Engine 4.27.2 for Myst. This is where it’s about to get a bit more technical… buckle up!
