UBlueprintPathsLibrary::MakePlatformFilename

function Engine Blueprint Since unknown

#include "Kismet/BlueprintPathsLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Converts a normalized "Unreal" pathname (forward slashes) into a filename using the current platform's native path separator conventions.

Caveats & Gotchas

• OutPath is an output reference parameter, not the return value — in Blueprint this shows up as a second output pin, not the node's return.
• This is a pure string transformation; it does not check that the path exists or resolve it in any way.
• On platforms that already use forward slashes natively, this can be a no-op — don't rely on it to validate or clean a path.
