CharacterMotor from the beta version 4.6 (2014)

Hi,
I am completely lost with this new scripts.
Firts I put this script to my “Avatar”. I have a Rigidbody and I use a terrain.
So even if I am not using the gravity, my avatar is falling ! I even freeze the Z position. I know it is a beta version but I was so excited because of the news features !
One quick question it is for 3D ? or “just” 2D

You can ask in the Beta group, where our developers could help.
