UBlueprintPathsLibrary::NormalizeFilename

function Engine Blueprint Since 4.20

#include "Kismet/BlueprintPathsLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Converts every '/' and '\' character in the path to '/', producing Unreal's canonical slash convention.

Caveats & Gotchas

• The result is returned via the OutPath output parameter, not the return value — in Blueprint this shows up as a second output pin, and in C++ it means the function has no meaningful return type.
• This only fixes slash direction; it does not collapse duplicate slashes or resolve ".." segments — use RemoveDuplicateSlashes and CollapseRelativeDirectories for that, or MakeStandardFilename to do all three.
