I'm looking to render out a video or image for display on Google Cardboard, i.e. a video is rendered with two barrel images, one for each eye, side by side.
I've found tutorials like the following: https://www.youtube.com/watch?v=1S-AATilv84
But I know that Blender now has Multi-view rendering capability so was wondering how to render for Cardboard from Blender without rendering an image/video for each eye, which the tutorial tells you to do.
Found it!
Once you have set up your animation or single frame:
In your Scene tab enable Views and select Stero 3D
Select the Camera on the scene and go to the Camera tab. Sort out the interocular disctance this should be 0.06 = 6cm, the distance between your eyes. Set Lens to Panoramic
Go to the Render tab, change the Dimensions -> Resolution to be the resolution for a single eye (this will depend on the android phone you are using)
Again, in the Render tab scroll down to the Output and change the Views Format to be Stereo 3D. Set the Stereo Mode to be Side-by-Side.
Press Render or Animation depending on whether you are creating a single image or a video, and you should be done!
Check an example output here: https://youtu.be/fEFmGVymbUg (Which annoyingly youtube currently seems to be converting to different 3D formats!)
To render for VR, see this: http://b3d101.org/en/vr/
There is another set of options on the 'save as' dialog, and you need to set the 3D option and the side-by-side option there too.
See https://www.blender.org/manual/render/workflows/multiview/usage.html for a lot more detail on this.
I am copying what I said at 3D render - requested side-by-side but got anaglyphic - how to fix to make it available more widely. This should be a comment but I don't have the reputation.
