Taking a second look at that, though - is that really a continuous projection? Or is that storing different parts as different chunks (and maybe projected differently) put together into the one image?

Some parts are continuous projections, like the face and torso, which are "closed" geometric objects. I don't know exactly how the HL human mesh is, whether separated in different chunks or fully joined in a single 3D object, but either would work if the faces are properly pointed to the specific pixel regions

it's definitely just mirroring the side of the head at runtime
