Problem with my Polygon surface

Hello,

i am modelling a motorbike helmet at the moment and i came across a problem with my polygon surface.

I am posting 3 pictures. 1 with just the Polygons
1 with Hypernurbs
1 rendering.



When i render, i get this silly area on top.

I cant solve it.

I would appriciate any help.

Greetings
Konstantinos

that's what happens with a SubD Surface (HyperNurbs) and a sphere type surface that all comes to a point - you can't fix it by taking the central tri's out an substituting an n-gon - it is possible to fix it (if you don't want to reconstruct the helmet) by adding in loops as the polys 'tighten' at the top like this

Thanks a lot.

So you mean, the way is to give as many loops as possible. But that means you will always have a false small area on the center, right.

Thank you for your quick answer.

you don't need tons, just some extras like in the example getting tighter towards the top at about half the distance of the last one (so to speak). (turn off the HNurb to see, of course) but it gets invisible without too much work
