That “options” should be replaced with different arguments, so the command should look like:
C:\Epic Games\UE_5.0EA\Engine\Binaries\Win64>UnrealEditor.exe “C:/Perforce/Dark&Evil/DarkAndEvil.uproject” -run=WorldPartitionConvertCommandlet “Persistent” -AllowCommandletRendering > C:\output.txt
By the way, if you add -ConversionSuffix, the converted file won’t replace the original one. A new file will be created with suffix _WP.
New command:
C:\Epic Games\UE_5.0EA\Engine\Binaries\Win64>UnrealEditor.exe “C:/Perforce/Dark&Evil/DarkAndEvil.uproject” -run=WorldPartitionConvertCommandlet “Persistent” -AllowCommandletRendering -ConversionSuffix > C:\output.txt
