I took the realistic rendering demo and built it for GearVR following this video -> http://www.twitch.tv/unrealengine/b/644059937
The good news is, UE on android can recognize this controller I got -> http://www.amazon.com/PG-9025-Bluetooth-Controller-Android-Samsung/dp/B00HA4O9G0/ref=sr_1_7?ie=UTF8&qid=1434011431&sr=8-7&keywords=ipega
The bad news is that both views are being squashed together into the left eye, with black in the right eye. They appear horizontal side by side, and the left view has a crazy ripple effect on it. The weird thing is, objects in the view do not appear squashed, but that may be my brain compensating.
EDIT:
BTW, I have the screen rotation bug, might this be the problem? It doesn’t affect anything launched through the GearVR thingy, but I have been launching this from its app icon.
