Yeah, I’m using the workaround suggested by asmithey. It’s causing my files to inflate quite a bit because of all that mesh data for every animation that didn’t use to be required, but at least I get my animations in now.
I just changed my export settings to Maya 2013.3 and it worked like it used to. Unreal just doesn’t like FBX 2014/2015/2016 it seems.
