UKismetMathLibrary::Matrix_GetOrigin
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Returns the translation component (origin) of the coordinate system represented by the matrix. This is the fourth column (W column) of the matrix.
Caveats & Gotchas
- • This reads the W column directly without perspective division. If the matrix encodes a perspective projection rather than a transform, the result will not be a meaningful world-space position.
- • The returned FVector is the 3-component W column; the fourth component (W=1 in an affine transform) is dropped. Use Matrix_TransformPosition to transform actual positions.
