Hmm, what's up next? Well, we have the concept of subdivision transits. Look for these on renders of meshes you see later. They MIGHT be highlighted in YELLOW depending on the picture you look at... Ahem.

Subdivision transits happen when you go from a lower poly mesh to a higher poly mesh all of a sudden. V3 has a nice even line around her face where V2's face was subdivided to make V3s... but we're looking at feet here, so I wanted to make sure you cn see some on her foot mesh. These are they.

I'm the asshole. You wanna be a shit? You gotta go through ME.
