Yesss, i managed to start with 1 player character.
I just extracted and put everything from data.pak into my mod folder, mod is without dependancies, the mistake i made before was not building the scripts. so after some edits and doing just that. Voilla!
I did my best to set all trigers to player1, removing any mention of player2, considering my inexperience with coding i prolly made some mistakes so i wont publish until i've played the game some more. Aside from that player1's model is not there in chargen(not being loaded) so cant customize appearance but can change skills&abilities without problem.
after looking into chargen problem, ill move onto unrestricting gender specific stuff and custom class preset. then playtest
