UKismetMathLibrary::MakeRotFromYZ
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Builds a rotator with Y fixed as the right axis and Z adjusted for orthogonality. X (forward) is computed as the cross product. Useful for aligning objects to a slope while keeping a defined right direction.
Caveats & Gotchas
- • Y is the primary axis and is preserved; Z may be slightly rotated to achieve orthogonality. If you care about both axes equally, use MakeRotationFromAxes instead.
- • Zero or parallel inputs produce degenerate results without error.

FRotator Example
Align foliage to a slope keeping a defined lateral axis C++
FVector SlopeNormal = HitResult.ImpactNormal;
FVector ConstantRight = FVector(1.f, 0.f, 0.f);
