Although it may seem that there are many posts related to that, I couldn't find any tangible solution to my problem, based on the following images, I couldn't get the smooth surface for bronze arm rest curved support. I have tried followings modifications w/o success. This discrepancy also affects the light map creation.

  1. Edge splitting,
  2. Recalulate Normals
  3. Change Auto smooth to 30d

The problem is that your faces are triangles. Triangles are notoriously difficult to smooth-shade.

The short answer is that you need to convert your triangles to rectangles (quads).

To do that, you can take advantage of a built-in Blender tool: "Tris to Quads." Select all the faces that you're having trouble with. Then press space and type "tris to quads" and then select the matching command. This will automatically combine triangles into quads, where possible.

But this might not quite work the way you want it to. If it makes awkward quads, you might have to undo that and try something slightly different. Try changing to "face select mode" and then select two triangles that would make a tidy quad. Then press space to run the command again. You might have to this for each pair of triangles, but it'll make the shading much more smooth.

So, avoid triangles where you can. Use quads as often as possible.

    $\begingroup$ Hotkey for tris to quads. $\endgroup$ – Timaroberts May 20 '16 at 18:49
  • $\begingroup$ Thanks in advance I just added the final images that I got after applying the tris to quads command( I don't have enough reputation to post more than 2 links so I deleteed the old ones). Regarding that I 'd like to know is this the best that I can get in terms of smoothness from Blender, to achieve more refinement do I have to apply subdivision or am I still missing something fundamental? $\endgroup$ – Sonya Blade May 20 '16 at 19:26

    $\begingroup$ @Sonya You should probably replace one of those recent images with one of your original images with the triangles so it relates to your question. $\endgroup$ – Dontwalk May 20 '16 at 20:04
