I gotta be honest, that wasn’t very clear. “360 panoramic interactive VR” sounds like a regular 3D VR experience to me. Side by side stereo video is what I described, it’s a VR video.
The fixed perspective SBS video you want can definitely be done by having 2 scene captures, an eye distance apart, and exporting their captures every frame. I would personally recommend against that kind of video though, since having a video stuck to your view is not comfortable.
First, start the engine with the following command line arguments: -usefixedtimestep -fps=30 -notexturestreaming
To start the engine with command line arguments, it’s easiest to create a shortcut to the engine (<Engine install location>\UE_4_<engine version>\Engine\Binaries\Win64\UE4Editor.exe) and add those parameters to the end of the Target.
Next, create a new actor with this Blueprint: Render frame sequence posted by anonymous | blueprintUE | PasteBin For Unreal Engine 4
And this function as well in that same actor, set to Pure: Add leading zeroes posted by anonymous | blueprintUE | PasteBin For Unreal Engine 4
Finally, add 2 scene capture 2D’s and 2 of the above actor to your scene, and reference the scene captures in those actors. Set up the variables on the frame export actors correctly. Hit play or simulate, and a frame sequence will be exported.
