@Ceryni:
Danke für den tipp mit blender. Werde es mal ausprobieren

@Superku:
Thanks. I know how to extrude and I created a robot yet. But I want to start creating a game soon. I wrote my thoughts about my game down and Created the first Terrain + first scripts. And now I need a Charcter, wich is the player.

Thanks!
Regards
