UKismetMathLibrary::Conv_VectorToRotator
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Returns the FRotator that represents the orientation in which the vector points. Roll is always zero — only Yaw and Pitch are computed.
Caveats & Gotchas
- • Roll is always 0. If you need to preserve roll, use a quaternion-based approach or compute roll separately.
- • Passing a near-zero vector (e.g. FVector::ZeroVector) produces an undefined/garbage rotation. Guard against zero-length vectors before calling.
- • This is a BlueprintAutocast node — Blueprint silently inserts it when a Vector pin is wired to a Rotator input, which can produce unexpected zero-roll rotators if roll was intended.

FRotator Example
Make an actor face a target C++
FVector Direction = (TargetActor->GetActorLocation() - Actor->GetActorLocation()).GetSafeNormal();
FRotator LookAtRot = UKismetMathLibrary::Conv_VectorToRotator(Direction);
Actor->SetActorRotation(LookAtRot);See Also
