First, right click the model and click "show in element viewer" then click "model". Right click the model again and click "add override materials". Go to the element viewer, click materials and then click octoling_girl_teamcolor. Right click that, press add attribute, click string, and type in $alpha. Do that same thing to octoling_girl_teamcolor2
Hope this helps!

Actually, no, whatever you do, DON'T DO THAT!! This makes the model never have hair again, unless you unsubscribe and subscribe again. Sorry.

But everytime i do that the eyebrows are gone how can i keep them and just lose the hair

go to the hair root right click go to utilities and then add scale controls. then make it as small as you can.
