I compiled and improved the maya plugin to work for maya 2016 and I also fixed some other bugs since my 2012 release.
You can find it here:
I looked into fallout 4 support and ran into some issues completely unrelated to the maya plugin and actually coding the thing which stopped me from updating it.
A part of the plugin is made in a special way and I can\t integrate the new fallout 4 mesh system. Honestly if I didn't have a job and didn't run into these problems I would have probably at least managed to get support for basic meshes. I pretty much need to copy the existing code and reroute it to take the mesh data from the new structures introduced with fallout 4.
But I am stuck at a point where I can't even code despite knowing exactly what to do. And I don't like Fallout 4 that much so I don't have that much motivation.
