Thanks for help. Found it.
It is on 100, so the 3D models should apear in every Zoom Level. But i found out, everytime, i load a game, i have to change the Tactical-View Zoom Level. Then it works.
But Impulse doesn't start now anymore...so i can't get Version 2.3, cuz after reinstallation it got back to 2.2.
Anyway, important i have the lovely 3D-Models again
No I only have to win a game and don't get slaughtered, but that's an other part of the cake
