FBX Exporter
I spent countless nights fixing Unity's FBX Exporter. The code sucks, the exporter sucks.
With my version you can actually export skinned meshes properly with animations etc.
It's been really long since I made it so honestly don't remember exactly what it helped with but it was bones and skinned mesh renderer exporting to FBX.
Pro Tip
FBX is the most supported file type by the Exporter, even Unity's.
