I want to save a couple of values, of witch i don’t mind some to be editable externally( not very important) and some to never be edited.(NEVER)
Are ue4 saves externally editable? How can i make them not editable if so?
Just making sure, if they actually are editable players could edit stats :confused: so probably not.
