I just tested this out and it works perfect with the EsenthelEngineSDK Path, however it doesn't appear to work with the Game Data Path. I get the following message.
"The Path to your custom Game Data folder
has not been specified.
Please don't forget to copy the "engine.pak" file.
My Autoupdate tool is located in C:\EE\EsenthelEngineSDK\Tools
My EsenthelEngineSDKPath is C:\EE\EsenthelEngineSDK\
I have shortend it to ..\..\EsenthelEngineSDK\
This works!
My Game Data Path is C:\EE\Game\Data\
I have shortend it to ..\..\Game\Data\
This does
not work!
However I have noticed that setting ..\..\Game\Data\ as the path for the Editor works correctly. So it just seems to be the Autoupdate tool that has a problem.
