Noob Render Question: Gouraud smoothing?

I’m new to Blender, but pretty experienced with other 3D software. I’m unable to find the “smooth render” feature, the one that enables Gouraud smoothing on polys. Looking at other people’s work, I realize it has to be there somewhere, but is it considered an aspect of material, texture or render by Blender?

It’s in the editing buttons (f7) It’s labeled “set smooth”
btw, please read the wiki (so you don’t have to ask these kind of questions again :wink: ):

Btw, It’s not Guaroud (color), it’s Phong (normal) smoothing in Blender. This is rather confusing (as is 90% of CG terminology…)

Also confusing, Phong actually proposed two ideas in the
same paper. One is the above reflection model; the other is
commonly known as Phong shading. Phong shading refers to
the technique of vertex normal (linear) interpolation. The term
“shading” is often carelessly employed in computer graphics
to indicate (among other things) some sort of interpolation;
for example, Gouraud shading means vertex color
interpolation. It might be worthwhile to stop using the term
“shading” as applied to Phong or Gouraud shading and use
the term “interpolation” instead.
The distinction between a reflection model and an
interpolation model is very important. This distinction permits
many combinations for surface rendering, such as using
Gouraud interpolation with the Phong reflection model,
Phong interpolation with the Phong reflection model, or
Phong interpolation with Blinn’s reflection models.7

Except for smooh radiocity.

Sorry to have posted such a basic question…I have, in fact been reading the Wiki, but several hours of searching and practice attempts had gotten me nowhere. I guess I was just looking in the wrong place.
Well, back to lurking…

If you have the bandwidth, you may want to download some of the video tutorials here - .

They are very in-depth and at a pace that is easy to follow. GreyBeard does a great job of telling you all the in’s and out’s and why’s while he is modelling. Highly recommended.
