How to enable dynamic resolution changing of dynamesh?

[archz2]

Dynamesh does not change the resolution once I convert regular geometry to dynamesh. What should I do to enable changing the resolution after I have pressed the dynamesh button?

I have to undo and go back to my original meshing in order to do dynameshing with different resoution.

I made a screen recording of what I face in Z-brush while dynameshing.

Hello @archz2

There has to be a change in the geometry before DynaMesh will retopologize it. Every time you reorder the geometry with DynaMesh, ZBrush will only adjust the surface that has been edited. This means that areas that already had nice polygon distribution will keep them even after the retopology operation. Do a slight sculpt on the mesh then do a DynaMesh operation.

Hi @archz2

@zber2 is correct. However I would also add that if you enable “project” in the Dynamesh menu, it will will force Dynamesh to redraw the topology every time, so any changes to the resolution setting will update itself with every Dynamesh.

Awesome!! Thanks a ton! ‘Project’ is the magic button. One query. Is there any way to calculate estimated polygon count that a particular number combination in dynamesh will give before I hit the dynamesh button or proceed dynamesh conversion of the geometry? I mostly go with trial and error by moving the slider to get an estimate. But I feel there’s a smarter way to go about it instead of waiting for dynamesh to happen for multiple slider settings.

I started off with 25.9k polygons, then it got converted to 4.016 million polygons. Resolution setting was 1296.

In order to see those they would have to actually be calculated . You wouldn’t save any time over simply performing the Dynamesh process, which is very, very fast if Projection is not enabled. Dynamesh is designed for speed as a rapid resurfacing tool to quickly create sculpt-able surfaces, effective at low to medium levels of detail.

The DynameshUtility plugin can set a target polycount for Dynamesh, but this is only going to be effective to about 2or 3 million polygons. Dynamesh is not designed for the capture of very fine detail.

As I mentioned, Dynamesh is a tool for rapid resurfacing up to about a medium level of detail, and does not have advanced options for managing topology like other options in the program do. What is it you’re trying to accomplish? Another tool may be a better fit.

Awesome! Thanks for providing insight as well giving me thumb rules that have contributed significantly in understanding the fundamentals.
