Howdy! First post, extreme UE newbie here. I’ve got a Gear VR (Note 4, Lollipop, Snapdragon, UE4.8.1) and I’m trying to learn Unreal Engine so I can try making some content. I followed the “Up and Running with Gear VR” Twitch training video Sam made. It was very helpful, and I was able to replicate what he showed, BUT! The judder is terrible in the headset. Whenever I turn my head quickly I basically see double, almost like it’s rendering twice and blending the frames or something, hard to describe. Very nauseating. I thought maybe it was a frame rate thing, but I couldn’t get any improvement with monkeying with it (like locking the frame rate to 60). I realized that when creating the project I had selected the “First Person” template that was under the “Blueprints” tab rather than the “C++” tab, so I started from scratch and did it all again but it worked just the same.
Digging through these forums I saw the old post where they pointed to a template for a Gear VR environment that works, the project is called “Gear VR Lighting” (it was uploaded to Google Drive) and features a number of multicolored spheres rising and falling. After auto-upgrading the project to 4.8.1, this works perfectly for me, no judder whatsoever, head tracking is silky smooth. Of course I could just copy this project and use it as a base for everything, but I really want to understand what I’m missing. I have tried comparing the two projects side-by-side but haven’t turned up anything useful yet.
Then I tried creating a new project using the “Flying” template. This built and ran fine on my GVR, but it had no head tracking (not entirely a surprise, though I would like to understand how to add it…). I also noticed that, despite having no head tracking, it had the same judder (or whatever the turn is for what I’m seeing) when I move my head. It’s like it is trying to do the head tracking but then snapping back to the vehicle’s forward direction, so a feature that should remain stationary (locked to my face, since head tracking isn’t working) shakes violently when I turn my head. This seems related to what I’m seeing on the FPS project.
In case it’s relevant, I’m developing on Mac OS X. It doesn’t seem to be an issue so far (as far as I can tell) but I was disappointed to hear Oculus seems to have left us out in the cold. I’m hoping I’ll still be able to develop for Gear VR on my Mac in the future, but we’ll see.
Anybody got any ideas for me? I’m just starting out so I don’t know how to do much yet. Just trying to get a foundation! Thanks in advance!!
