Creating animations for Unity models using Blender? I am relatively new to Unity.

Currently, I am trying to make some animations using the free model Unity-Chan available from the asset store. Could someone post some helpful tips or perhaps a link with a brief walkthrough on how to perform this?
This is very simple:


First export your model from unity: http://wiki.unity3d.com/index.php?title=ObjExporter

Add animations using the rigging tools
Export FBX to unity using these settings:




Done!
