    It actually is possible to do stereo panoramas correctly. Blender has implemented it in Cycles. http://code.blender.org/2015/03/1451/ They basically rotate the camera pair for every pixel you render. It is described in this paper from Paul Bourke in more detail. The only downside is that I think you can't do this with good performace on a current GPU (which isn't optimized for rendering one pixel frames). But maybe there is a clever trick for doing it with a hardware rasterizer.

    I suspect that even these 360° panoramas are only an approximation since the name BoxReflectionCapture implies that there are actually taken 6 images which are then warped accordingly. But I haven't confirmed this in the source.

      You can get a decent stereo-pano output using a combination of (lots of) cube captures, sliced spheres and a hell of UV work.
      We got some nice results, but the workflow is kinda heavy on a 980... anyway, just check the link and have a look.
      We're planning to rewrite the whole thing from the ground-up as a real plugin, since in its current shape it's not even by far prime-time ready!
      (Of course, the stereoscpic effect works 360, but horizontally only since the virtual camera rig is parallel to the ground.)

        I've been doing a lot of playing, and testing with this Plugin over the last little while. One of the tests I did was made public on YouTube, as it fit within the time frame that didn't crash in the Google metadata fix. One project I tried this with was 6.5 minutes long. The metadata fix would not work with it. But the one below, at 2.5 minutes or so, worked fine.

        My biggest problem was that lightmaps do not work well with this plugin. I needed to make every object that was close by, movable to get around this problem.

          great plugin.
          i have one problem though.
          when i render out a panorama, i get seams in each eye.
          i believe these seams are eye cube textures, although i'm not sure.

          any nudge or push in the right direction would be greatly appreciated.

          this is an image of the seams from a stereoscopic mp4 made in After Effects from the Left & Right HDR files.

            Need another software to make these images into video

              @EVRTOP I would guess the issue is that post process is done in post, after reflection capture is done. It won't work with this method.

                HI! I get beautiful 4k 360 frames from your plugin. Then i import left eye in After effect and i create a mp4 using custom h.264 with bitrate to 240 and key frame set to 1.
                Then i start to have a nive HQ 360 videos. But very heavy. So Kolor eyes have problems to play this guys and also when i try to upload in youtube... are so compressed and the result is not so good.
                Have you some idea to create a 360 video not so heavy and with higt resolution? Maybe h.264 have to reduce the resolution?
                Another cuestion. Once i've rendered 2 eyes y create a stereoscopic 360 video with ffmpeg but the result is impossible to visualize with kolor eyes. Maybe too heavy because the h.264 is too high def? Someone can suggest me some other software to create a stereoscopic video? Thank a lot.

                      Awesome job!!

                      How do you make it work without having your engine built from source code (blueprint only)?
                      I would really appreciate your support.

                        Can someone explain to me how to turn the left and right eye HDRs into a stereoscopic video file using Adobe After Effects, please? And what to do to put it on Youtube as 360 stereoscopic video?

                        Monoscopic is working for me, but I'm struggling with the stereoscopic workflow.


                        p.s.: moderators, sorry for the double-post, I just realized I posted to the wrong thread before

                          Hello,

                          I'm having a crash with this plugin in UE 4.9.1, and maybe anyone has experienced the same here. It's happening in the moment of rendering, when I execute the bat file and it doesn't renders 1 frame. When I play the game in editor it works and begins rendering at a random/performance-dependent framerate(here is the problem when you need to output video).
