So I seem to have figured out a solution for anyone else having a similar issue. I just had to have the alternate user edit their customs on the main steam account that the game was originally bought on. Then I saved that UDK customization file so the other user could just copy and paste it when they log into their account. Hopefully that makes sense….
One more questions. If I bought skins on my account and then was able to share the game with another user on my PC shouldn’t there also be a way to share those skins? Strictly on one PC with a shared user of the original account. Any help on how to make this work? No luck so far :(
