Or what governs what hair type will be hidden by a helmet? The problem I am running in to is HairMaleNord04 is clipping through the Helm of Yngol and the Ancient Nord Helmet and probably others. I see that HairMaleNord16 (mohawk) is hidden by the helmet but HairMaleNord04 is not and surely there has to be something controlling that but I cant seem to find it. Both hair types are identical in the CK save for the model so now I am at a loss. Is there something in the hair nif controlling this?
