How can i rotate a Vector3 direction 45 degrees along the y axis? So a Vector3(1,0,0) for example, would become Vector3(0.5,0,0.5). And i cant use Transform.RotateAround, or any other Transform methos. As i am not applying this Vector3 directly to a object.

http://unity3d.com/support/documentation/ScriptReference/Quaternion.AngleAxis.html That's a general case. For rotation around a world axis, it's faster/easier: For (1,0,0), this results in (sqrt(.5), 0, sqrt(.5)), not (.5,0,.5), by the way. The length of the rotated vector stays constant. To achieve a squared hypotenuse of 1, you add .5, 0, and .5, not .25, 0, and .25, which would shorten your vector. Thanks, this works great.

Glad to hear it. Rotate those vectors like they were on the Witches' Wheel!

That operation is dependent on the order. rotatedVector = Quaternion * vector OK rotatedVector = vector * Quaternion won´t works and will launch a compiler error
