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

I can't do anything, I'll say it right away. And I won't have time to create or learn anything. But if I'm given ready-made models, I'll spend 5 minutes of my life and export them into the game ;)
It would be great if the models were in Maya 6.0 format, but I think I'll find a converter from 3DSMax to Maya if needed.
