Shading issue

Hey Roxana,

It’s a bit hard to tell from the screenshot, but it almost looks like inconsistent Normals to me…

Did you try the good old SHIFT+N (in Edit Mode)?

Can you provide a link to your .blend, please?

It’s just, that aprt from Geometry, there are so many combinations of settings in the Bevel Modifier, that can easily mess things up: like in the right Cube I changed one setting only:

I think Jonathan Lampel does a far better job than I can in: https://cgcookie.com/lessons/smooth-flat-and-custom-normals

You’ve probably seen it already, but now is the time to re-watch it and understand better what it means.

There was a question on the forum some time ago, about why the Auto Smooth Angle field was greyed out and it took me over an hour to figure it out…now, I know where to look and I also had to revisit mentioned Lesson, because I didn’t know exactly what was happening.

But of course, feel free to ask, if you want more information, after watching Jonathan’s explanation.

There is a fun little-known shortcut;

if you are in Edit Mode and press R, that will (obviously) Rotate the Selection, but if you then press N (so: R, N), Blender will Rotate the Normals of the Selection…you’ll see nothing happening, but you’ll have created Custom Split Normals!
