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

you can't just reduce the model size; it becomes impossible to apply effects to the creature, and movement issues start to occur, and the death animation can't be changed either :(

What about increasing the size? This is not an idle question – when I assign a large size to creatures, they initially stand normally on the battlefield, but after the first attack, they shift to a corner of the square they occupy.
