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

take a look, will this version work in the mod...? this is a simplified geometry; I baked the normal map from the high-poly throne onto this one, and then I made it gray in Photoshop, like stone... it's clear that the chair itself is essentially smooth; all the bricks on it are just drawn on. I did, of course, go over it a bit with a brush to mark some of the protrusions that should be in the place of the bricks, but the simplified geometry doesn't allow me to clearly define each brick.

P.S. I think it might be possible to do a retopology, placing polygons strictly along the bricks, according to their shape, and making the gaps a depression, but that's a very time-consuming task, and I'm not sure how many polygons it will require. It will certainly be fewer than on the high-poly model, but I don't know if it will be significantly fewer, as there are a lot of stones...
