Hello. Having some horrible problems dynameshing objects in Zbrush x64. Trying to get one watertight mesh with 10 millions points but even with 7 million I get this:
This is a completely wild guess but instead of increasing the DynaMesh resolution try increasing the size of the model under Tools > Geometry > Size > XYZ Size. My thought is that at very fine resolution the algorithm is messing up, but larger size and a smaller res might change the math to work.
Dynamesh really isn't designed for going that high, it's meant to be
used in the blockout stages of a mesh, and then you just subdivide
normally from there.
For 3d printing I need it to be dynameshed that high. Question is not about why I need this, it's I get artefacts when going over 5 mils of polys with DynaMesh.
My suggestion wasn't to reduce the amount of polys. Increasing your mesh's size in world space will increase its polycount after Dynameshing, as Dynamesh's resolution is set in world space.
The result you're getting is similar to what happens when you Dynamesh something with a hole or twisted, self-penetrating polygons so I'm wondering if Dynamesh is hitting some kind of precision error that would change with a larger mesh and lower Dynamesh resolution.

The "why" is important because there may be better ways to solve your problem but that depends on what you're trying to achieve.
If you're trying to use dynamesh to retopo an existing object then you could duplicate your object, dynamesh at a fairly low resolution then subdivide it and reproject your details from your source mesh.
