wavy reflections on a smooth hemisphere

[speltospel]

As you can see the mesh is made smoothly. Even in Face mode there are no waves. Is it possible to somehow avoid such reflections?

I guess there is some tiny distortion of the geometry and this is the result. Have you tried modifiers like Smooth (not TurboSmooth) or Relax?

OpensubD already assigns 1 smoothing group to the geometry. So this doesn't change the situation.

The relax modifier also does not correct the situation. but it also affects the ribs of the "cap". which is unnecessary to do.
Yes, I could separate the top and do the relax only for the top part. but this detail was modeled using relax.

You can try to create sphere primitive with many segments, non-uniformly scale it and try to fit to the shape of cap's top as close as you can, then select cap mesh's vertices that are "wavy" and conform them to the sphere with new conform modifier (must have Max 2024 or newer).

I created it using approximately the same method, Conform tool. in the Ribbon panel.

If you see wavy reflections, that means the geoemtry is not perfect. Create a new sphere, scaling it down, assign the same material and check if the reflections on it are wavy (they will probably be good).

The mesh may looks good but it can have such imperfections, which come down to topology and mesh smoothing modifiers.
