What a fantastic plugin for getting gLTFs out of Maya!
I just had a crash in maya and had to open an autosave version.
It looks like any animation group information was completely wiped out and not saved.
I can pull in from a good previous Maya scene, but this seems like a bug and not a feature IMO.
Ping @Guillaume_Pelletier (I hope I’m piging the right person 
)
Hello,
Thanks for using our exporter.
Basically, the animation group are saved to file user properties.
I do not know if Autodesk is auto-saving those properties. If you send me the corrupted file i can have a look to see if the SDK is detecting the properties but fail to load it or if the properties are simply gone after the crash.
Regards.
