    Really nice , I'm trying to prototype an asymmetric VR co-op game on one PC .
    I'm quite new with BP .

    What do we have to change/add to be able to use the standard 3rd person character and animations that comes with the engine content ?
    Everything is set up to target a pawn actor.

    Thanks

      I don't think this is possible without modifying source code unfortunately, and I wouldn't know where to begin. I'd search and see if people have been able to do "split screen" but on two monitors. nDisplay might also be an option, but I'm just brainstorming here.

      I'm assuming that you'd like to use the 3rd person character BP for the player controlling the Spectator Mode Camera. You can't use "Add Movement Input" without possessing the pawn, and since our player controller is possessing the VR Pawn, the workaround would be to use an AI Controller for the 3rd person character, and add the SceneCaptureComponent (just like in the example project) to it.

        Thanks a lot for your reply Victor.

        Would it be possible, using this method, to recreate the same walking/jumping effect that a normal character has and the interaction with other actors ,such as pick up or move an object in the scene?

        Also , for the only purpose of the VR asymmetrical local multiplayer , could this tutorial be more sutable for my needs , instead ?

        So I would only need to somehow add the Vr Player in it .

        Thanks in advance.

          Yes, but you will have to do the input similar to how we did the flying camera to execute walk/jump/etc.

          It's a good tutorial but in this case we can't use two player controllers like a traditional local multiplayer game does. The tutorial series then goes into how to set up a networked multiplayer game which we don't need since everything is local.

            I know this is a bit late to the party but I am stuck on a part of the application and thought a little help could be useful.

            Is it possible to use the actual mouse cursor on the window to work with the widget interaction instead of having a world cursor for the widget interaction component?
            When I set the mouse cursor to be visible and click on the window the widget interaction gets all messed up. and the mouse goes off bounds on the window.

            Thanks a lot in advance and I hope I am not doing something terrible posting here after this time.

              Gabe23K Not at all! That's what these announcement posts are for

              You can't use the regular mouse cursor because we're already hacking it by adding a 3dwidget component in front of the camera. My theory as to why it goes off the screen is probably because it's trying to operate within the screenspace of what's being rendered to the HMD, and not in the render target texture that's being displayed on the flat monitor.

                Yeah, I imagined. But no worries.

                I ended up going a bit deeper with my research and found a solution for the mouse cursor. Using the widget render target as the texture for the Spec Screen instead of adding it in front of the camera and Setting the Relative location of the widget interaction instead of just adding to it. It was rather satisfactory merging both, your approach and the other one, into a solution for this.

                Thanks for the hard work and the reply!
