Thanks again for you answer.

1: I also don't know how they look. It just don't looks like the ways in modern games a seperate model... So i wonder how to get such good paths or something like that. Ancient roads or whatever. Woulnd't it be a lack of geometry using a seperate model just for 2D street use?

2: So you mean a sprite with quad? Then i need much sprites rotated and all centered? So no model but a collection of sprites? And then a good shader?

Thanks, Simon
