yeah, the car will get smoother - I will convert the polygones to a subDidivision - you know ? so, at the polygon-model I need to model the raugh body of the car - and than it will be a high detailed modell. but I don´t know how I shoould make the detail in the polygons, to get a good result when I will convert the polygons to the subdiv. that´s my problem, thx bernhard
