The orientation of the daydream controller seems incorrect (definitely points in a different direction from the Vive controllers) which also results in the Widget Interaction component pointing the wrong direction.
I’m testing with the controller emulator app in the UE4 editor preview mode.
I have a project with a Widget Interaction component attached to a motion controller and debug mode turned on. The trace for the Widget Interaction is like offset by 90° to the right?? The same goes for any mesh I attach to it (here is a visible Arrow).
Anyone else seeing this? Is this a known issue? UE4.14P2
