- Open P4V
- Log in with the perforce account that you want to use in UE
- Go to Connection > Environment settings, a window will pop up
- Check “Use current connection for environment settings” checkbox
- Click OK
- Open UE
- Go to Tools > Change Revision Control Settings
- Select Provider “Perforce”
- Check “Use P4 Config” checkbox.
What it does is it sets up system environment variables that UE reads and uses to log into your perforce server. There is no password stored in UE itself. I haven’t figured out how to use a P4CONFIG configuration file, yet. Anyone ?
