Black Faces...

Hey everyone, I am having a bit of a glitch in Maya, and was wondering if anyone could help me out with my problem. Whenever I am in shaded mode, some faces seem to go black. I have attached an image to show you guys what I mean......Can anyone help me out with this one?

Regards

Wierd I have seen grey like that before but not black.... maybe make sure the black areas dont have 2 faces stuck together... or see if the normal are facing the same way.

Try :

Edit Polygons > Normals > Set Vertex Normals.

Hey guys thanx for the suggestions.

Kurt.....I checked all the normals and they are all facing the same way, and i also double checked the 2 faces thing, and it's all good. It's wierd when I move around in my viewport the black dissapears and moves onto other faces....WIERD???

Mtmckinley....Thanx 4 the help. I am using NURBS for the model though, any idea with any NURBS commands like that?

this is definately not a video card driver problem...

Whenever I am in shaded mode, some faces seem to go black. I have attached an image to show you guys what I mean

how can this be a NURBS model and u have "faces" that turn black.

this is a common thing in polygonal modeling. usually set normals to face or like mike said set vertex normals solves that problem.
i really doubt videocard drivers has anything to do with this....

Hey vladimirjp......I meant to say NURBS surfaces....anyway, I have recently formatted to win2000 and updated drivers and it is still doing the same thing, but whenever I click on the actual surface the black dissapears. This is one wierd case, yip yip.

Have you checked the direction of the surface normals?
("Display>NURBS Components>Normals (Shaded Mode)")

I have to agree with the 2nd response from mtm. Just take it one step further;
Edit Polygons > Normals > Set Vertex Normal > Options
Unlock Normals might be off. TURN THEM ON
