I've been said that using 3Dmax you have a toll that calculates the shapes with less polygons and trying to keep it as acurate as possible and I haven't tried it yet.
The not so easy part is that using zmodeler if you have a very detailed shape you just have to do a new one but using less polygons, right?.....but those shapes don't get as lower polygons....
I guess there's no other way....
Can you help out with normals?...what's the best way to calculate them?
thanks
