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

Who else will be on this model?

It's too late, and I wouldn't want to waste a month and a half of work.

Okay, anyway, there's no way to avoid repeating models.

By the way, can you show screenshots? (icons of artifacts, creatures)
