For those that know unity shit well. Which of these animation parameters is the one that changes the normal map of a mesh? 

Like what is it called? there's a billion of these and I can't figure out which of these changes a normal map. I'm making an animation that changes my avatar's texture (which eventually will go into an on and off toggle) but I also have to change the normal map or it looks off. I figured out which one toggles the actual texture, but now I need to toggle the normal.
