Chrome Texture rendering problem in Maya

[captonjohn]

I'm a beginner in Maya and recently I created a bathroom scene by following a tutorial. I did everything correct and applied all textures smoothly but when I rendered then chrome texture to metal objects didn't rendered properly and all metal objects which were created by NURBS looks black. I tried to find out the solution but didn't got it because I don't know what is the problem due to which texture on NURBS object is not visible on rendering.

Can anybody suggest something about it?

Here are the screen shots of texture settings and final render.
