The last build of the 3D MVC Build by @afedchin was Kodi 17.6 back in Dec 2017, @afedchin was unable to continue development for Kodi 18, but @Morpog has stepped in and has now seems to have got Kodi 18 Leia working with MVC 3D and has provided a test build.
I have tested and it seems to work fine, so far.
I will update this page as I test it further.
Download the latest test build from link in first post in the Win – Intel HTPC/NUC’s w/reliable Kodi-native 3D MVC Playback Kodi forum.
