#AutoFBX: Automatic FBX exporter for Blender
- Right click and save the following link: https://cdn.rawgit.com/lukeadams/AutoFBX/1.11/autoFBX.py
- Install it in Blender User Preferences under the Addons tab
- ctrl+g objects that you want grouped into one file
- -groups/.fbx will be created in the same directory as .blend on every save, overwriting already existing files with the same name.
Using it with Unreal Engine, works great!
