When Raul equips an NCR ranger helmet, or a variant thereof, the back of his head clips through the helmet. I have heard that ghouls who are NCR rangers have this problem as well, and also that the problem applies to certain other types of headgear, although I haven't confirmed it myself. I would be eternally grateful if someone could fix this. As far as I know, using Blender or Nifskope to edit the male ghoul head (meshes>>characters>>head>>headghoul) and flattening the back of the head ever-so-slightly would do the trick. Unfortunately I'm having a really hard time figuring out Nifskope and this is as far as I have gotten. Hopefully it would be quick and easy for someone who has experience with editing meshes. Or, if there's some other, better solution I haven't thought of, that would be great too; like I said, I'll be eternally grateful to anyone who can fix Raul's head clipping through helmets. P.S. I already tried making the helmets in question use the "head" slot in the GECK, but this unfortunately causes the character's neck to become invisible. Also, I am aware of this mod but unfortunately, editing Raul's facial features in the GECK doesn't fix the issue with the back of his head.
