How to make the surface look smooth, i have used the modifiers I've modeled a "yakult" bottle with a mesh cylinder, and have used a modifier tool (Subdivision Surface and Smooth) to make it look soft. I'm happy with the results on a solid preview, but when I render, It looks like a line which is stripped or surface lines appears.
the question is, how can I make the modeling look solid and smooth on render preview? What should I do?
I have taken a sphere and added Subdivision Surface Modifier to it with the view 2 and Render 0



As you can see the sphere look smooth. But when i hit render i get this render



Flat or un-smooth sphere

Reason is the setting in the subdivision instead of Render value 0 make the same value of 2

And you will see the same result seen in the 3d solid view.
