Hi, and Happy New Year.
I found that when testing using IE the Stereoscopic Cardboard is visible, but using Chrome no fake VR was available. You are better testing through the Krpano server to make sure all is working correctly. Once it is live it should work fine.
Krpano cannot handle direct cube maps, a bit of slicing in photoshop is required, this is a bit of a shame seeing as the Gear VR can read them strait from the render. I hope this is something that could be implemented in Krpano... Especially as VR it is getting a lot of use and press from the CGI community lately. It will however handle Side-By-Side spherical images from Vray, but these are poor in quality compared to Stereo Cube Maps.
If there is a lot of interest and I have the time I could do a Step-By-Step, but there is loads of programmers on here who can give better advice than me from that side of the software.
Here is our festive one if you want to check it out.
