having the option to purchase what your tori looks like, kind of like how you paint cars. and you could buy it in a full set or in parts, so you could have maybe a matte head and a gloss body.
e.g styles:
- gloss
- metallic
- matte
- more that i cant think of right now

these are things that couldn't be done with actual textures since they dont give reflection feedback the way the different styles do.
I don't have images but you should know what these words mean.
