Several things I need to address here.
>Original model was dozens of materials, one for each section of the atlas, and some of these were 1024x1024 blocks of a single color.
>A UV map is basically a guideline for the textures to wrap over a model, think of it like an unfolded box or origami piece, only things don't necessarily have to be the same size as they truly are.
>If something is going to be a solid color and not supposed to be detailed, you could just shrink it to miniscule levels.
>The dots represent vertices, points where the polygons end and new ones begin. They're the creases on the metaphorical box folding. It's kind of small, but the shape of the dense bit at the very bottom is clearly the side view of my avatar's coat.
>The author of this MMD model made the torso of the avatar, the central, largest, most dense part of the model, where I'd begin if I wanted to make clearly noticable changes to the model beyond recoloring, the smallest and most difficult to edit part of the entire thing, requiring me to remap the UVs of this avatar myself if I wanted to change the textures (which I've done before, EVERYTHING is this fucked)
