i'm a new maya user and would like to learn how to model a character but don't know how to start.
Try reading the tutorials here, there and everywhere
well there are a lot of tutorials out there no one pretty sure can explain here how to model nurbs patch modeling course it requires some experience and to explain how to do this may take long time and may seem complicated when you begin modeling first time best i can think of to advise is to go to this section http://www.boris3d.de/tutorials.htmlthere are plenty nurbs patch tutorials at least they will give u the concept of U V and how to attach torso with any other body parts just briefly nurbs patching requires using attach , detach tools also stiching and rebuilding UV's so check that site and see for yourselfand also there are many ways to do this the easiest way is to project curv on surface and then attach to torso again not comletely good way of modeling u can also draw curv on torso and make sure torso is set to make live so that u can draw in U V space and then when complete just open/close curve and then attach body parts to that curve i don't recommend using this style on nurbs the best result u can get is to use nurbs patching or go model in polygon and then convert to subD courve it will be same as u model in nurbs patch
good luck
yes patching pretty much requires you to know what exacly you are doing wich is very bad news for most newbies.
lot of trial and error required im affraid.
