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

Yeah... I opened, for example, a gnome on a bear – the model consists of several parts – the bear, the gnome, the gnome's helmet, the gnome's axe, etc. So, the bear has 1000 polygons, the gnome has 1600, and the other parts are, of course, smaller... So, you need to aim for each part of the model to have no more than 1500-1600 polygons, and the entire model should be around 4000... approximately... what a mess!
