Just like the Normals and Speculars are a separate var, the Diffuse and Gloss maps are also a separate var now. This way, a future look can refer to these two vars for the textures, without having to share the other dependencies (like clothing and hair) with Yuki.
I'd make a single var out off all these textures instead but it's not possible. Because the textures are 8K, the package would be larger than 500MB which seems to be the hub's file size limit.
