Albertosauru

This is a real, Albertosaurus, and it is in the game, I think one that he looks sickly? I suggest to convert it to a decrease Tyrannosaurus, a problemma I do not know how to make mods for this game, please create a living creature such a fashion
PS I am from Uzbekistan, and I do not know much English if any living creature knows Russian contact me on the forum

I forgot to write something, is it possible to create a 3d-max their models of dinosaurs and their place the file in the game? I was told that because of the private motor that is not possible
