UBlueprintPathsLibrary::RootDir

function Engine Blueprint Since 4.0

#include "Kismet/BlueprintPathsLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns the root directory of the entire engine install tree, one level above EngineDir(). Equivalent to FPaths::RootDir() exposed for Blueprint/Python.

Caveats & Gotchas

• Not the same as EngineDir() — RootDir() is the install root that contains Engine/, and (for source builds) the project itself if it lives alongside the engine.
• In a packaged standalone build this typically resolves to the directory containing the game's own Engine/ folder, not a shared engine install.
