So since i was unable to do any face imports or edits of the hair this is the best we get for now XD a Claire Cosplaying as her big Sis Jill !!!! Special Thanks to Mr. Crazy Potato For fixing stuff for me and theflyingmuffin for the base mesh
You can do it yourself actually. Just go the files inside the folder and delete the Jill hair for the default Claire hair or you can replace the jill hair files with ada's hair files.
I've never done it before so I'm still confused on how to do it xD
If you go under this directory, "Claire Valentine\natives\x64\sectionroot\character\player\pl1000" you should see a folder and a file that has the name pl1070 and that is related to the hair related portion of the mod. So for example, if I wanted Claire's default hair instead of the Jill hair. I would just delete the pl1070 folder and the pl1070 file then keep the rest and proceed with the normal install.
