hi guys,

i have a problem: i'm modelling a car at the moment, i built the rough surfaces in nurbs and then converted them to polys. sometimes a strange thing happens: after i combine two patches and merge the verteces together, the edge is rendered smooth in the viewport. in the pictures below, you can see that sometimes it only appears partial as well... i know it has to be a problem with the normals, because when i average them, everything appears smooth, but thats not what i want...the face normals all point in the same direction.

do you have any clue? maybe its a stupid problem, but i'm quite new to maya...

thanks a lot!
