The stereo layer component does not seem to be working in Daydream. I setup a simple stereo layer that has a non-live texture that is working on the Vive however it does not show up at all on the mobile device when exported.
I doubt that would work unfortunately (but not sure 100% sure). So it’s only good for some purposes, but for showing a texture that does not change often it appears to be working very well with no performance hit
