RTF is a global modification that replaces all towns in the game.

Today, I retopologized the hair and dress, plus I added the throat and teeth... I trimmed the body hidden by the dress and hair; in short, all together – hair, body, dress, eyes, teeth – is 15,500 triangles... but they are all separate meshes – the largest of them is the body with 10,000... well, I might reduce the polygon count on the shoes by another 1,000-1,500... that's it, but there's also a fur cape, so... and all the throne accessories have 9,000 triangles...

How do these numbers look?

Given my "creative" abilities, I'm afraid I can't reduce it further; we should aim for these numbers... but, I think you said that separate meshes are better, right? If I'm not mistaken, then the maximum mesh is 10,000 faces, and all the meshes together are 25,000.
