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

On the weekend, I tried to attach dragon skull pauldrons to a lizard warrior and failed :( The horns pierced the lizard's neck, and my ideas ran out.
Then I updated the dwarven riders :)

Now I have learned how to cut pieces properly and export models with multiple textures into the game.
Now I am thinking of attaching a necklace made of skulls to an unupgraded lizard infantry unit, and giving upgraded units pauldrons from old screenshots
