smooth render problems

[waner_garouche]

Hi,
How can I have a smooth render of an object without changing it geometry?
I can't understand why sometimes the render of this Panton chair appears smooth and sometimes it appears bad. I suppose that I have to change some properties of the render options but I don't know what option to change.
Thanks

If you apply materials to the group/component instead of the faces inside you'll end up with faceted geometry.

Sorry guys, I've found the response to my answer in this forum : I just have to explode and then to regroup the object to have a smooth render.
