How do I loop a legacy animation type in unity 4?

How do I loop a legacy animation type in unity 4? Also, is there a FAQ on how to get existing characters working using the new mecanim system? It looks like it’s only for 3rd person player characters.

Hi! I just figured this out - when you import the animation, in my case I imported a .fbx file, it should take a while to load it up. When it does, you click on the object, and then click on the Rig button in the Inspector. Turn the setting to Legacy, and hit Apply. It should take a minute. Then click on the Animation tab and change the Default setting to Loop. Hit apply and it should work. Let me know,
good luck,
