Hey,
I have searched everywhere for the actions I wrote before and cant find them, but glad that you got the vector thing working.
If your using a 2D plane then the look at probably would not work as I believe it uses the Vector3.Forward in order to rotate the object (this would effectively make your plane disappear as its forward for this would be on the wrong axis.
I saw somewhere on a website an FBX Plane that had been exported from 3dsMax with different axis settings. Something like that might help?
Regards,
