Did you upgrade Windows 10 to 1709, Fall Creator’s Update? I personally have not tried it. The main issue is that the THETA V uses UVC 1.5 for webcam standard, not UVC 1.1 that the THETA S supported. I think there’s some other issue with UAC (audio) 2.0 that got upgraded in the Windows Fall Creator’s Update. NOTE: I don’t know if it works on Windows 10 1709. I want to test it and was planning to soon.
Can you test Unreal3D with a Mac? Does the IDE run on a Mac?
See this for the Mac.
