Hi! How did you move your eyelashes to scar section? Is there a tutorial somewhere? Or is that your own CC?
I don’t know of a tutorial but it’s pretty simple. Basically download Sims 4 Studio. You might need to unmerge the file which can also be done in S4S.
Open the unmerged files one by one and change their type in categories to „occult eye socket”. Make sure it’s socket and not eyelid, that one only shows up for vampires. Also Apply To All Swatches, then save.
Once you’re done merge the files again. Make sure to make a new file and not just overwrite the old one. Otherwise the change won’t register. The name can still be the same though.
Not sure if you've seen it, but you can unlock the occult categories for all sims with a mod from crilender. It's helpful to be able to layer skin details and such.
