I am so damn confused by thickness. What the hell even is it?! At first, I thought it meant how fat your character is, but I wasn't sure so I did more research (it could be how fat the pc is, and I am just overthinking this). By using the custom mannequin feature under appearance, I thought that it was just shoulder width. but then I read somewhere that its how fat the pc is and now I am confused as all shit! Someone please explain this shit to me.
