My object can have any(unknown) rotation in the world.
I need to interpolate this object's local UP-axis, towards the World's UP-axis, without touching the object's other local rotations.
Anyway, all I seem to manage, is interpolating every object-axis towards every World-axis at the same time, effectively aligning my object to the World, like a well trained nazi-soldier.
I'm using this code to accomplish my faliure:
var TopQuat:Quat = Quat(0,0,0,1)
transform.basis = Basis(Quat(transform.basis).slerp(TopQuat,delta))
Any hints for isolating this interpolation to my object's local UP-axis?
