Hi folks. I’ve been hearing about KiteAndLightning’s plugin coming soon, but have heard no official word from Epic on the matter (It’s in their hands now). I got tired of waiting, so I built my own using captureCubes, BPs, Materials, and Matinee. No plugins required, but there is a pretty serious limitation. 2k x 2k per eye. This is a hard limit on how high a captureCubeTarget can be set. Even with this limitation, the resulting sideBySide 4k x 2k panos are still pretty nice, so I’m totally willing to share the solution until a better one comes along. Here’s an image to show what it can spit out.
There are some improvements to make, and a few bits I need to clean up, but the method is working. This image is a sideBySide stereoPano. There are some minor seam artifacts that can be improved upon, but this serves as a base method for correct stereo on the 4 main axis. Zenith and Nadir can be problematic, but I’ve been negating stereo on them in finals anyway.
Many thanks to RyanB for making this possible, the math of which can be found in this thread.
I understand completely that captureCubeTargets were never meant to be used this way, but I would ask that their resolution limit be unlocked, so that exporting higher resolutions could be done. It would be very useful! (OK, now that I’ve unlocked the higher res renderTargets, I see why you left them at 2k;) It’s not for the feint of heart. It’s very, very slow, and eats ram for breakfast. It can also crash your video drivers due, I suppose to hogging up video ram. Buuuut, with care, you can get it to work.
UPDATE: Got 8k animated stereoPano export working. Here’s a vid.
Note, YouTube has not at this time enabled stereo360 vids. So in an effort to showcase the working stereo aspect, I left it as a normal video but with red/blue stereo enabled. As soon as YouTube gets that switch flipped, I’ll update the video for cardboard and gearvr.
