Hey, just a suggestion.. maybe try smoothing it out. I don't know exactly what you mean but do you convert it to polys or something after your through with nurbs? if so then use the

Edit Polygons>Normals>Soften Harden> Options and set it to soft or hard, up to you. Like i said I haven't had that problem in a while and i haven't used maya in a while, but maybe that will fix it user added image

My guess...and it's only a guess, is that somehow you got the surface normals reversed on one or more of you're NURBS surface patches. But I can't see how. The only way I could get them to flip was with the suface editing tool.

if you display the normals, do they all still point one direction?

can you post the file? I'll take a look at it for you.

What version of maya is this made in?

Try applying a different lambert to your file. Middlemouse drag it on user added image

. Lambert, blinn.. w/e. Just try another texture now that its attatched.

you want the matching numbers (14 in your case) to be the same direction. Right now, they're opposite.

Select one of the surfaces and go to Edit Nurbs > Reverse Surface Direction > Options and choose Swap. This will swap the direction without editing the flow of the surface.
