The problem with the resolution DynaMesh

ZBrush Usage Questions

Hi for all.

People, please help solve the problem. I am working on the reconstruction of a large monument and part of it consists of 5 pairs that holds the hands between each other. Initially, I worked on each pair separately. But as you can see in the presented images, all pairs are holding hands, that is, in the end it should be a solid model, which I then need to cut into technological parts for production.

The big problem is that when I use DynaMesh, the number of polygons, with the maximum settings, is limited to about 4 million (you can see small polygons on the faces that are in the image), despite the fact that the basic number of polygons, before DynaMesh, was more than 65 millions. Ie a lot of details were lost.
And before the merger and recounting of the overall composition with DynaMesh, each pair was also used DynaMesh in process of creating, but the resolution was twice more.

So the question is, how can I increase the resolution of DynaMesh recalculating the model?

The figures are created in full size - approximately 1.8 meters high.
I also tried to increase the models by 2-3 times to increase the resolution of DynaMesh, but, unfortunately, the result does not change.

Hello @MonacoFelice

Please be sure to read the documentation for Dynamesh. You’ll note that Dynamesh is a tool intended for establishing form at low to medium levels of resolution:

DynaMesh has been designed to create low and middle resolution sculpting stages, making it a perfect way to create your base mesh before diving deeper into all the powerful traditional ZBrush sculpting and editing tools.

There is a practical limit to the amount of detail you can capture with dynamesh. All those figures being Dynameshed together is a whole lot of surface area for Dynamesh to cover.

At some point, depending on your output goals, you will need to transition to a traditional multiple subdivision level process to reach the upper end of Zbrush’s detail potential.

The quick and dirty way to do this (which may be adequate for a print or CNC process in conjunction with Decimation Master), is to simply subdivide the mesh as needed, continue sculpting, and Decimate the highest level of resolution to make it manageable in pre-print software.

If your topology needs are more exacting, for instance for UV and texture work for digital render, it would be best to use Zremesher to create a clean, low poly version of the fused geometry, subdivide it as necessary to receive the incoming detail, and use one of the methods on this page to project the detail from the original hi detail version onto the new mesh.

Once accurate form has been established, the need for frequent dynameshing will diminish, as you are no longer making drastic changes to the form, but rather working on fine detail. At any point if you decide you do want to change the topology again, you can use the projection process above.

Thank you a lot for the answer, SPYNDEL. Your advice is very helpful.

Also, as a workaround, to get high detail or remeshing part of the local area, I use Sculptris Pro mode.
It really slows down very much when working with such a high-poly model (even after Decimation), but still allows to make the necessary adjustments locally.
(it is unfortunate that Sculptris Pro mode does not work with the model, when part of the model is hidden, …otherwise, it could greatly simplify work on such tasks)

So, I decided to ask on the forum to make sure that there is no direct way to increase the resolution of Dynamesh.
Thanks!
