I know you can make Xian and Sam B invisible to zombies by modding their Spectre and Decoy skills to -16/3 with the save editor. I've done so and it works great. What I want to know is, how do you make the other 3 characters invisible? Some people keep telling me that you can add Xian's skill tree to other characters to use her spectre skill with them but it never seems to work (aka stick) for some reason. When you load up the save, it shows multiple skill trees ( in a messed up fashion) as if it's worked but when you play the game, the character is NOT invisible. So how is it done so that it sticks on the other characters? I need some help with this. I want to make a set of invisible starter saves and I want it to work properly. I've tried to get help on another modding site, but the people there were just plain rude or ignorant. I hope there is someone here kind enough to help me. Many thanks in advance.
