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

Have you ever worked with it? I don't understand how to export it... maybe you could upload these files to the forum, there are only 9-10 of them?

When I don't use a program for a long time, I quickly forget everything (I last opened MAX in 2021). I think I did it like this -

I also vaguely remember that something happened with the animations, and they sometimes broke (the X, Y, Z coordinates, etc., were messed up). I had to edit them manually in "Track View - Curve Editor" (deleting unnecessary keys). I also remember changing the controllers for Position and Rotation (sometimes I set it to "XYZ", sometimes to "Bezier"). But I can't remember the circumstances or why I did it (whether it was for export, or maybe I just had to "polish" them after importing).
