how can open 3vr?? in cityengine or viewer?
a quick query in the help
my Question about how to open the file 3vr with this extension again
I don't have it installed but this thread mentions the viewport window
There is also a blog post:

AFAIK there is no other way besides Gear VR to actually view the file. You also have to upload it to ArcGIS Online and then use a beta app to download it again, after which you can view it offline. Unfortunately you can't just put the file on your phone right away and there's apparently no way to view private 3vrs, so this is a pretty public affair.
