Hi, am having an issue. Well, nodes are really aggravating to me, so…
I want to make a metal texture on the metal parts, of course- but even with gloss, the glossy effect only appears on smooth shading, but not flat. On flat it just looks matte…
Of course, I don’t want to turn it to smooth shading because those are hard edges and it is not smooth!
Not sure,what your goal is. But you have several options (maybe more).
Try to increase faces. on flat surfaces (sub division modifier).
As I understand it, Smoothing makes from QUAD surfaces, TRIS.
Your lamp arms are just long quads (surfaces of 4 vertices).
Solution could be to add more quads (subsurface modifier).
When using sub surface modifier, you can try this.
and / or
An other trick people use is to create additional edges close to (along) other edges, which need to be sharp.
