Thanks for getting back to me so quickly.
Thats strange you don’t see them get marked for add, did you open the Events folders and look at the files? If you don’t have those folders open when you open the project they don’t get added. As soon as you start looking in any of the FMOD related folders Unreal “sees” them for the 1st time and tries to add them.
Attached is an image of the Revision Control submit screen and my ignore file.
Something of interest is that the Content/FMOD/ and !/Content/FMOD/Desktop lines are making the ignore file work correctly in the Perforce GUI. If I try to mark for add there I get the same “The following files were not marked for add…” pop up as you showed above.
