Hello, I wanted to weld points in one selected area of the model, If there is a way I would be glad for some ideas. To be specific it is a border between two polygroups that appeared after combining parts with the boolean operation. Polyframe lines are concentrated on each other and overlapping. At first, I just smoothed this area but it revealed some topology distortions, then I tried welding points which brought satisfying results, but the process affected the whole model, not just the unmasked area which is undesirable.
Hello @Astroteles_Evetrials ,
Is this a decimated model? The topology quality looks poor for the purpose of getting good sculpting or painting results in ZBrush. Unless this is a model you are decimating for export, you may consider simply ZRemeshing it into quads to clean up the topology.
I don’t recommend randomly merging points on your mesh. This has the potential to create problem geometry.
If you want to keep those polygroups and draw lines along the borders, enable the “Keep Groups” option and ZRemesh at a high target polycount. This is a good idea to do after any boolean operation because they create awkward or problematic topology in the places where the meshes intersect. Your results will be impacted here by the fact that your polygroup borders are uneven in areas, and not cleanly separated. Otherwise leave this disabled, and ZRemesher will eliminate those polygroup borders.

Hi, thanks for the reply, yes the model is decimated it was supposed to be a final mesh before 3d printing but realized I had to change something though I don’t like tools like Dynamesh or Zremesher in the late stages due to lousing details (even with ultra resolution Dynamesh can cause some points to stick together in narrow spaces like bricks etc). I will try Zremesh with a high target polycount and see if the result is satisfying.
The point of ZRemesher is not to capture fine detail, but to redraw base level topology quickly and cleanly. You would still need to subdivide the mesh and project any high res detail from the previous mesh to recapture fine detail. This applies to Dynamesh as well. These are tools for quickly redrawing topology over a low-to medium detail form, not for capturing high res detail directly.

Generally you’re going to have much better results if you complete your mesh editing prior to any Decimation. That should be the last stop for the mesh on the way out the door, or the first stop to put an especially dense mesh in range of other features, like ZRemesher, for which it would otherwise be too dense. Decimated geometry is going to make most mesh editing or sculpting in ZBrush far more challenging.

Good afternoon , I’m sure the solution to skin problem will be Best RF Microneedling . You can expect significant improvement in as little as 3 sessions. Depending on the age of your skin and the severity of the problems you are dealing with, you may need a few more treatments. A good rule of thumb is 1 treatment per decade of age. Thus, if you are 50 years old, you may need up to 5 treatments to achieve the desired results.
