What's Wrong with Quaternion Rotation in the Game Engine? Steps:


I created two identical objects, and animated them to rotate 360 degrees.
I used euler for the first object and quaternion for the second.
In the Viewport they rotate the same, but in the Game engine
the second object is rotated differently.

From Hawkenfox:

"This issue seems to be an unsupported feature at the moment. Can someone mark this question as answered?" 

(Okay - I am posting this answer, pasted from your comment, for the purpose of marking this as an answer and closing the question. Please mark as answered.)
