Hi,
What is the difference between Dynamesh and ZRemesher? What is the advantage of using one over the other?
certainly reading the docs on both would explain it very well.
i’d say dynamesh is for retopologizing while you sculpt and zremesher is for producing a clean, lower poly count version of what you sculpted using dynamesh.
i think of dynamesh as dynamic tessellation without the “dynamic” and zeremesher as Decimation Master without the decimation.
Dynamesh creates topology that essentially only cares about maintaining the surface volume while providing a consistent density of polygons (in order to create a model that is ideal for sculpting on). It’s not exactly the prettiest wireframe nor the most efficient, but it can quickly get the job done. This comes in handy when you’re doing things like pulling limbs from a sphere, merging shapes together, and preforming boolean operations. With a high resolution it can be used to capture finer details, but because of the consistent density across the entire mesh this can lead to some pretty high polygons counts without the advantage of stepping between subdivision levels.
Zremesher is a slower process, but it takes the time to analyze the surface of the model in order to create an edgeflow that actually flows along with the surface. It also lets you use curves to guide the resulting topology, while giving you the option to control the density in specific areas. When used correctly, it can even create meshes that are fit for use in animation and game engines.
The best way to see the difference between these is to load up a model, run dynamesh on it, and then remesh it. Here’s an example of how each interpret a model. You can see that zremesher has a nicer flow to it, but doesn’t always use consistently sized polygons.
Generally if I were doing a character from scratch I might start with dynamesh while building out the main shapes, but once those are established I’ll either Zremesh it or manually retopologize it so that I can work with subdivision levels again.
thanks for the explanations and clearing things up… Very new to Zbrush and many things seem redundant to me at first, although they’re clearly not like Dynamesh vs ZRemesher, or SubTools vs Polygroups vs Layers xD
