My motion controllers are not shown in UE4.11.2. I had a working proof of concept yesterday but the controllers where out of batteries. Now when launching the poc it does not work anymore. Yes I have a Oculus DK2 setup with latest drivers 1.3 but the rift is NOT attached to the desktop. In the test scene (that worked yesterday) when I press the menu button on the motion controller, a menu is shown and the controllers are visible in the menu BUT when playing the scene they are not tracked. It did work yesterday so I have no idea what to do. I tried disabling all other plugins than the SeamVR plugin in the plugins section of UE (as suggested above) but still nothing is shown. The Steam VR is active and all lights are green which means setup seems to be ok. Any help is more than welcome.
