Alternative Vectors
Alternative Vectors are vectors that can be used as the Forward, Right and Up Vectors.
Alternative Forward Vector
The Alternative Forward Vector direction will ignore the Pitch rotation and only be on the XY axes.
It is the equivalent of only using the Yaw for the Forward Vector:
Alternative Right Vector
The Alternative Right Vector direction will ignore the Roll rotation and only be on the XY axes.
It is the equivalent of only using the Yaw for the Right Vector:
Alternative Up Vector
The Alternative Up Vector direction will only be on the Z axis.
