It’s 2018 now and I’m using 4.21 with Perforce.
I just renamed a file and submitted it to source control.
Source control now contains two files, one with the old name, one with the new.
When I use “get latest version” (from P4V) on a different machine, I get the following error (and that’s the old name):
Quite a horrible first time user experience with Perforce, I must admit.
EDIT: Apparently you must rename files from within P4V itself, and not from the Unreal Editor:
I wish Epic would have disabled the rename option from the context menu when source control is activated then, and this could have been avoided…
