UKismetMathLibrary::Conv_Vector4ToQuaternion

Description
Converts a FVector4 direction into a FQuat orientation that points in that direction with no roll. Preserves the world up vector, similar to Conv_VectorToQuaternion.
Caveats & Gotchas
- • The W component of InVec is ignored — only XYZ direction is used. Passing a point (W=1) instead of a direction will still be treated as a direction.
- • If you don't need to preserve the up vector, FindBetweenVectors(ForwardVector, InVec) is faster because it avoids the internal FRotator construction step.
- • The input vector does not need to be normalized, but passing a zero-length vector produces an undefined result (quaternion identity in practice, but this is not guaranteed).

FQuat Example
Orient an actor toward a world-space direction stored in a Vector4 C++
FVector4 FacingDir(1.0, 0.5, 0.0, 0.0);
FQuat Orientation = UKismetMathLibrary::Conv_Vector4ToQuaternion(FacingDir);
