Flags

Unreal Engine command-line flags are passed to the executable to specify certain behavior. For example, to run the Unreal Editor with the DumpAssetRegistry flag, use

UnrealEditor.exe -DumpAssetRegistry

Command-line arguments are not case-sensitive. This means the following commands are all equivalent:

UnrealEditor.exe -DumpAssetRegistry
UnrealEditor.exe -dumpassetregistry
UnrealEditor.exe -DUMPASSETREGISTRY

Keyword Arguments

The following table contains a list of Unreal Engine command-line keyword arguments. The syntax to run these commands is -<Keyword>=<Value>.

For example, to run the Unreal Editor and specify to listen for incoming online beacon connections on port 8888, enter:

	UnrealEditor.exe -BeaconPort=8888

These commands are not case-sensitive, therefore the following commands are all equivalent:

	UnrealEditor.exe -BeaconPort=8888
	UnrealEditor.exe -beaconport=8888
	UnrealEditor.exe -BEACONPORT=8888
