UKismetMathLibrary::Conv_MatrixToRotator
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Extracts the rotation component from an FMatrix as an FRotator (Pitch/Yaw/Roll in degrees). Assumes the matrix represents a transform without shear.
Caveats & Gotchas
- • Scale in the matrix is ignored — only the directional (normalized) component of each basis vector is used for rotation extraction.
- • If the matrix is scaled non-uniformly, the extracted rotator may differ from what you'd get by normalizing rows first. Normalize the matrix with GetMatrixWithoutScale before calling this if scale accuracy matters.
