I have never been a fan of the HGEC GUTZ body, but I do find it appropriate in one case. I would like to use it for the Orc body, while using the regular one for the other rest.

Is there a way to use Gutz for just the Orc race only?

I have heard talk of the possibility of doing it through scripting, by checking a "race" token and displaying a mesh based on that. I'm not aware of it having been done, and I've been looking.

The answer is: if there are folders or files specific to orc this can done.
Edited original answer as this isn't the mod I thought at first.

As I had answered in your other thread, this kind of thing has been asked many times, and the answer is that it generally isn't possible due to how the game has race meshes setup. The closest you'll get is some very script heavy mod which switches out items, or redirects mesh paths to work with a certain body mod. And as far as I know, that project has been dropped due to complications related to the method, and it only applied to the player. Any sort of adjustment for everyone based on race simply isn't possible, no matter how many times it's asked, or how many times people attempt it. There are no angles left. Even using a sort of tail body doesn't work since it would require a total replacement of all equipible meshe, would run into severe clipping issues, and still would not provide the functionallity you are looking for.

This is what I do. I create a new race using the different body type and then I change all orcs to the new race. haha. My lizard women are all Mystic Elves and my cat women are all ahnime (but have no voices?). There is a mod out there that changes orcs to better looking orcs and I use that -- Orcs are ok but lizard and cat women suck -- in my opinion, haha.
