Wow, You are Cool! Thank you telling me these details. My problem was solved, too!
I got some errors at the end of compiling, but the output files are work correctlly with Unreal.
Here is the error log:
Program.Main: ERROR: AutomationTool terminated with exception: AutomationTool.AutomationException: Failed to find command -Rocket
Anyway, I can continue my work now.
Cheers!
