How to react to recentering by the user with the home button in UE4?
There is mention of it being possible with Unity in the doc: https://developers.google.com/vr/unity/controller-basics#recentering
but nothing for UE4 My game is a 360 game where the menu can appear at any HMD yaw. Recentering with the Daydream controller always moves the HMD back to Yaw 0 which means my menu is then located somewhere else but not centered. Ideally HMD yaw is not changed on a recenter only the controller is recentered to the current HMD yaw. Alternatively we need at least an event.
I also requested some from google side here: https://github.com/googlevr-unreal/UnrealEngine/issues/5
but the issues section there seems dead.
According to the requirements: Daydream App Quality Requirements - Design | Google VR
unfortunately we do not know when the Home button is pressed so it’s not possible to calculate the offset.
For now I have done a dirty workaround in my blueprints to get it working but it’s definitely not ideal and would not fit to every use case.
