Deleting voxel artifacts (averaging small geometry) I need help. There is such a mesh. Obtained by importing the *.obj file from the fractal generator into Blender. The fractal generator creates this mesh using voxels. In this case, all sharp edges are obtained with this kind of &quot;voxel noise&quot; - sharp peaks, notches, zigzags, holes and other artifacts. This is similar to what we see in Photoshop when we look at the sharp edge of an object in an image when zoomed in greatly. The challenge is to rebuild this mesh so that the large and medium shapes are preserved, but these edge artifacts are gone. Is it possible? It seems that the most logical way would be some smoother, which would completely destroy all small geometry, averaging the position of the verticles. That would suit me. However, the modifiers that I tried (remesh, decimate, all 3 smoothers) do not give satisfactory results — they do not destroy small details, or if they do, then almost nothing remains of the original shape. And I would like, if possible, to do this without manual selection of verticles in artifacts regions, since in some cases the shape can be quite complex. Do you have any suggestions?
Not an answer ...

v01_Vertex Group
I wanted to isolate mess on edge by curvature with Pointiness node (only for Cycles), Bake ...

... and use this texture for VertexWeightProximity modifier to convert into vertex group to be used as mask for Smooth modifier.


v02_Sculpt Mask
Similar technique can be achieve by Sculpt mode. Expand by Curvature didn't work for this, but in the same menu is Dirty Mask that worked. So probably easier way to isolate ...


Smoothing
... but even separation was successful, using Smooth modifier (for vertex group) or Smooth Filter (for sculpt mask), it failed at the end for the same reason ... topology is too bad to get rid of those things.
Even I tried Remesh &gt; Blocks to get even distribution without small artefacts and than Smooth modifier (or any of a smooth modifier).
Sorry
So, probably only one advice I how - try Meshlab app that is announcing nice optimisation features specifically for thouse issues. But I don't have an experience to navigate you more.
