Ekozsoki- oops! I know there was some kind of tutorial somewhere...but apparently it isn't working

Luckily i still remember.
First you have to get a skintone that's already been linked to the slimmer bodybuilder mesh (

And then you simply replace the textures of that skintone with the ones from the skintone that you want (in the case of Dale, the stefan skintone)
