I did some hunting around and came upon this quote:
But no matter what I do I can't get this stuff working. It either only registers the "TB"-part and shows the alpha mask in one eye and the diffuse in the other - or the player crashes.The overlays they can be video (e.g mp4), and they can even be video with stereo+alpha if you have the grayscale alpha beneath the RGB and set the filename tag to _TBLR. I would recommend creating your VR overlays in Octane itself, as pano spherical renders, but with a cropped FOV, say 60 degrees by 60 degrees. If you render a 60 deg. FOV at 1024x1024 per eye, it should exactly match the res of an 18K cube map. This way you can do MP4 video overlays as 2048x1024 stereo sbs @ 60 fps, or 2048 x 2048 stereo sbs, with alpha under RGB @ 60 fps. We may add a mode to automatically place alpha below RGB, but there are many post tools that can do this for you before saving video, even photoshop.
The video is invoked by the following line:
Code: Select all
url = "tester_LR.mp4", fovh=31*2,35, fovy=31,
