1) There is nothing wrong with the placement of the objects here!
2) Its just that the surfaces seem to overlap (as seen in black in pic below), thus rendering as a black/dark surface!
3) This is not a problem when rendering closer!
4) So the objects isnt "really" overlapping.

I have to fix this for the rendering. Its the same result, of course with either poly or nurbs surfaces (I tried both out).

How can I fix this problem (besides moving the objects further away from each other)?
