UBlueprintPathsLibrary::FileExists
#include "Kismet/BlueprintPathsLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns true if a file exists at the given path, false otherwise.
Caveats & Gotchas
- • This is a synchronous disk (or pak file) check via IFileManager — calling it every tick for many paths can hurt frame time, especially on platforms with slow I/O.
- • In a packaged, cooked build only assets baked into pak files or loose cooked content will be found; arbitrary editor-time source paths will not exist at runtime.
