UKismetMathLibrary::Quat_MakeFromRotationVector
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Constructs a quaternion from a rotation vector, where the vector's direction is the rotation axis and its magnitude is the rotation angle in degrees. The inverse of Quat_ToRotationVector.
Caveats & Gotchas
- • The magnitude is interpreted as degrees, not radians. Passing a radians-based vector will produce incorrect rotations.
- • Passing a zero vector produces the identity quaternion, so there is no divide-by-zero risk, but intent may be lost if the caller expected an error.

FQuat Example
Construct a quaternion from axis and angle C++
// Rotate 45 degrees around World Z
FVector RotVec = FVector(0.f, 0.f, 1.f) * 45.f;
FQuat Q = UKismetMathLibrary::Quat_MakeFromRotationVector(RotVec);
