Description
Constructs and returns a quaternion from Euler angles in degrees. The angles are applied in Yaw → Pitch → Roll order, matching UE's standard FRotator convention.
Caveats & Gotchas
- • Euler angles suffer from gimbal lock near ±90° pitch. If you store rotations in Euler form and later reconstruct them, avoid storing intermediate values near the gimbal lock singularity — the round-trip will lose yaw/roll information.
- • The input FVector packs the angles as (Roll=X, Pitch=Y, Yaw=Z). This differs from how FRotator stores them (Pitch, Yaw, Roll). Convert carefully when mixing the two representations.

FQuat Example
Create a quaternion from designer-friendly Euler angles C++
// Rotate 90° around world up (Yaw), 0 pitch and roll
FVector DesiredEuler(0.f, 0.f, 90.f); // (Roll, Pitch, Yaw)
FQuat RotQuat = UKismetMathLibrary::Quat_MakeFromEuler(DesiredEuler);
