Can see edges/faces when rendering?

Hi all, first post here!

I don't know what this falls under but sometimes when i render a scene i can see hard edges and what seems to be a smooth cylinder/sphere and i was just wondering if someone could suggest a solution for now and for the future?

As you can see on the pipes (top right slightly) the edges are showing?

Thanks in advance!

I guess it's a spline (and not a mesh) you have to check your auto-smooth angle amount.

If it's a mesh (preferably a "poly") use the "smoothing group" section

That worked! =D

Thanks ever so much, is it possible for a quick run-down on what smoothing groups does?

I've seen it before but never paid much attention to it.

Glad I could help you. Check attachments for a "small explanation", you can use more than one smoothing group on a face. And if you want to use "fast" smoothing groups, check the "Auto smooth" function with the angle amount of "smoothing limit"

Easy explained it's a very easy & simple way to give a visual illusion that faces are "smooth" and blend into each other. You can do that for instance with a box too, with faces that have an angle of 90 (or even more).
It's easy to use smoothing groups for simple shapes to give the impression that they are smooth without using some turbosmooth-stuff or very dense meshes.

Hope this helps

Hi Miniminer!

Thanks for the explanation, as you can see below it turned out very well! =D
