Avoiding Unity's Automatic File Import

Since Unity does not provide a way to disable its automatic import of files such as Blender's .blend files, I thought I'd try to find a workaround that would still allow me to keep these files inside a Unity project's Assets folder. 

A Custom glTF Importer for Unity

I've never really liked Unity's handling of Blender files, so after doing a bit of research, I decided to write a custom importer for glTF files. It actually turned out to be less work than I thought it would be, and being able to extend the importer with additional custom properties has been very useful!
