Dimple smoothing

[Dudu Edri]

My dimple has the polygons visible on it, with subdivision surface enabled:

That’s before converting to a mesh.

When I enable Shade Smooth on the dimple I get the desired result, however when rendered it looks like that:

What am I missing?

Thanks.

Hi Dudu @duduedri96 ,

Go back a few steps. You need to set the Boolean Cutter (the UV Sphere) to Shade Smooth. That should make a smooth dimple.

Hi Martin, I did just that – the entire message above shows how it looks before converting to a mesh. The first picture shows how the dimple looks when not applying shade smooth to the UV Sphere, however when applying shade smooth to it it looks good and smooth (not shown with an image). However, when I changed to rendered view, I have that weird looking circle and dot in the middle of the dimple – as shown on the second image.

Are you by any chance in Orthographic view? I think that view tends to create artifacts. But this is a weird one. If you go into edit mode, does the middle dot disappear? If you zoom even further in, what does that middle dot look like? Can it be a whole in the mesh? You can also upload your file for use to take a look at it, go all Sherlock and see the mystery more closely.

Does your Boolean cutter have a black material?

Can you share the file via dropbox, google drive or similar?

Here’s the file:

2. after converting to a mesh: https://drive.google.com/file/d/1uLqCHgGoajmtFKaAAUYsjfufcj6vYj8n/view?usp=sharing

It happens after converting to a mesh.

I use no material and have no overlapping geometry. Maybe it’s related to the resulting topology?

I downloaded the after converting to mesh and it looks fine. Both in viewport and render:

Then I downloaded the before converting and it’s fine there as well. Just to test it out, try opening the file on a previous Blender version and see how it looks.

Hi Dudu @duduedri96 ,

That appears to be a lighting artifact caused by the new EEVEE. Compare 4.1 and 4.2:

So you can either use 4.1, or switch to Cycles.

Maybe there is a Setting somewhere in EEVEE, that you can tweak to make this better, but I haven’t found it yet. It is also very possible, that it’s a bug (4.2 is new and EEVEE is completely re-written, so that’s not unlikely).
