Set it to “shade smooth” and at “object data” set to “auto smooth” angle 30, give it a bevel modifier and a subdivision modifier. Now I have a cyllinder with a good continuous shade.
In edit mode I select a slice of the pie and seperate it. Now the shade on the side is not continuous anymore.You can see that the shadow is sharp at the separated part.
The angle inside the cut is outside the smoothing threshold, autosmooth is probably set to 30 degrees while the angles on the wedge are greater and won’t be smoothed. Turning up the value might fix it, but will cause problems elsewhere. Depending on what you want to do, you may have to have a separate complete object who’s visibility is turned down when you need the one with the wedge. Just an idea.
Thank you, I will look at it. I hope there is a possibillity to get the shade fluent. I read somewhere that you could do it with the “normal edit” modifier, but couldn’t get it right. Did not understand that modifier. Like you said, switching is allways a way to get around the problem.
You’re getting discontinous smoothing because when you break off a piece, you introduced a hard edged normal shading to the borders. Your cylinder won’t logically shade the way you want.
If you want continous normals, use “Data transfer” modifier on your objects, and use a whole, smooth cylinder as the source. This will copy the normals of the whole cylinder to match the other cut off objects.
