UKismetMathLibrary::Vector4_Normalize3
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintCallable
Description
Normalizes the XYZ components of the vector in-place, setting W to 0. If the squared XYZ length is below Tolerance the vector is set to (0,0,0,0).
Caveats & Gotchas
- • This is BlueprintCallable (not BlueprintPure), so in Blueprints it appears as an exec node that mutates the ref parameter rather than returning a new value — a different pattern from Vector4_Normal3.
- • The default tolerance is 1e-8 (much tighter than Vector4_Normal3's 1e-4), so very small but non-zero vectors that would be zeroed by Vector4_Normal3 may still be normalized here.
