I’m doing some automatization. When I invoke UnrealVersionSelector from console it shown Win32 windows with progress bar etc. Is there any way to supress it? Maybe -silent option? Or maybe you can add it?
Are you referring to running UnrealVersionSelector-Win64-Shipping from the Windows command console? UVS is essentially a GUI wrapper for UBT. Have you tried running UBT by itself?
There isn’t anything provided as part of the Engine that would help with what you are trying to do. If you need to be able to access UBT.exe from an external program, you would probably want to either create a config file with the path to UBT, or set an environment variable.
