zbrush cant increase dynamesh resolution

Loops

Hi everyone,

I have a very strange situation happening. I am importing a model from 3ds max and want to apply dynamesh. The thing is that I hit a wall with 4096 dynamesh resolution at 2 mill polygons, I need more. Whatever I have tried doesn't work. If someone could help me I would appreciate it a lot.

What I have tried:

• I tried Increasing the size of the model from 3ds max and bringing it to zbrush, but it doesn't seem to care about imported size.

• I tried Increasing the size of the model inside the zbrush, how much bigger it gets doesnt go higher.

• I tried applying dynamesh with the circle unchecked didn't do much

• I tried adding the DynaMesh Utility plugin in the ZBrush 2025 and 2022 ( it's supported for 2022) and couldn't make it work.

• I tried exporting from 3ds max in mm system units ( ZBrush works with mm system units)

• I tried applying decimation and re-dynamesh again but still nothing.

From my understanding something might be going wrong with the mesh itself because when I am trying to apply it to the default cylinder dynamesh goes without problem to 7 mill.

Does someone know what might be causing the problem ??

Most likely the object is too big.
iirc zbrush likes to work with objects that are 2x2 zbrush units.
If you click 'unify' in the deformations tab it should resize your object to a more "default" size. Or scale it in max.

I tried scaling it from max but didn't do anything. The unify though helped somewhat, it scaled up the model and from 900k I dynamesh it to 2 mill. Thank you for the response !

Update: The thing is I have a model and it’s going to be 3D printed. My main problem is that I need more detail to work. I needed the dynamesh because in a later stage I am going to separate it into different pieces in order to be 3d print ready.

My error was that I didn't know that I could use boolean without the need of dynamesh. I always was using Booleals in zbrush by selecting the Boolean I wanted ( for example subtraction ) then merge down and dynamesh. But now I saw that if  I have my subtools set to the right boolean operations I can click the "Make boolean mesh" in the subtool palette and it creates a new tool. Its the mesh that I see while previewing boolean (no need to remesh or dynamesh). 

This brings me to the problem presented in the thread. I needed more dynamesh in order to preserve detail. But with this info the work around is that I can use divide without needing dynamesh again, so I think that solves my problem. I can continue my work so that's good.

Still I don't understand how Dynamesh is supposed to work. It Should have applied more resolution by upscale it but it does nothing.

Dynamesh works at 2x2x2 grid or size of mesh, if mesh is above this 2x2x2 (too large etc) you will have variable dynamesh resolution even at 4k. 
Dynamesh is for concepting only, you will need to zremesh and divide it few times then add details back.
