Using Nisa's to add Eyelashes to NPCs

[hammerIN]

So I have been using Nisa's wicked perversions to add body details to npcs but though it has a setting to add eyelashes to them I can't get it to work. I've tried different eyelash packs and set it to 100% but nothing. Is there a correct pack that works or do I have to 'make' my own pick compatible with Nisa K's software somehow?

 

Thanks.
