Is there anyway to copy all FSM in a Unity 4 project back to Unity3?

You could export your globals and make all your FSMs as templates, then copy them to the Unity 3 project. The only thing is that importing globals didn't work for me with Unity 4, from 3 and from 4. Dunno if will work from 4 to 3.

Is that the only way?
I have many FSM. It is pretty hard to copy 1 by 1 in template.

You tried exporting a unitypackage?

The only thing is compatibility. Unity 4 has made a major change to the engine, so I don't know if a project will port backwards correctly. It does work from 3 to 4, but one has to do a lot of changes to completely port it to 4. Try to export a unitypackage and import it in a fresh Unity 3 project.
