Lost all cursor control and gameplay movement of the pawn

HELP!

When I test play my game from the UE Editor within the Selected Viewport, all my control over the Pawn has been recently lost. Keyboard and mouse control do not work. Nor does anything in VR work for rotating your head, etc. Only if I hit Alt-S when test playing and eject from the pawn can I rotate around the screen with the mouse cursor. Clicking Alt-S to re-possess the pawn leaves me stuck and unable to move the pawn/camera. They keyboard and mouse work perfectly fine when simply working in the UE Editor.

I started with a default VR template scene and have not done much to modify it. Previously, both the VR headset movement and the viewport/ keyboard/ mouse movement worked fine.

The issue started during a time when I tried making UI widgets. If I make and activate a 2d widget for swapping lighting scenarios, with two widget buttons that show up on screen in the viewport, the cursor DOES respond to that during gameplay. But the minute that I click elsewhere in the screen during gameplay to move the pawn/camera, again there is no response, no pawn movement at all. I have disabled these completely while trying to solve the issue to no success.

And oddly enough, this is not limited to one particular project, but several, including those I have not opened in weeks. And yet there is at least one or two other UE projects that work fine gameplaying from the Editor into the viewport using the cursor…

The loss of control has something to do with the VRPawn from the VR Template project. If I create a blank Unreal Studio project, which only has a Player Controller icon on the screen, when playing in the viewport, the cursor works to control movement. If I import and drop the VR feature pack’s VRPawn onto the screen, set the VRPawn to its AutoPossess to Player 0 and try to play again, the cursor does not respond and the player is stuck. If the VRPawn’s AutoPossess is on Default (or not to possess) then gameplay reverts to the Player Controller icon and the mouse cursor works fine.

So what is causing the Pawn to lose any link to the cursor to control movement? This is happening in all my VR-template based projects, so it does not seem to be a particular project’s settings… It happened in UE 4.22 and still happens after I downloaded 4.23.

What is wrong?! Without being able to test play anything, UE is basically useless to me.

Thank you for any help,

the ui issue part sounds like you’re setting the ‘input mode to ui only’ somewhere.

So where would I look to fix this? In the Editor preferences, not the Project preferences (since it’s happening on any projects that have a VR pawn)?
I even tried uninstalling UE completely, manually deleting any leftover folders I could find, and reinstalling UE, to no avail. Perhaps I missed some user preference ini file someplace.
Any ideas? Thanks!

if the issue is that the input mode is changing to ui only then it’s probably being called in one of the blueprints. either the bp where you create it or the widget’s bp.
…

it seems like you expect the vrpawn to have mouse and keyboard input setup like the default pawn. This isn’t the case as mouse/keyboard movement in vr is disorienting. So unless you’ve added mouse/keyboard movement input to the vrpawn yourself there’s no reason to expect it to move.

also I think what your calling the player controller is the player start.
