What are some common remeshing mistakes and how to avoid them?

由人工智能和领英社区提供技术支持

Remeshing is a process of creating a new mesh topology for your digital sculpture, usually to improve its performance, quality, or functionality. Remeshing can be done in various ways, depending on your needs and preferences. However, remeshing also involves some risks and challenges that you should be aware of and avoid. In this article, we will discuss some of the best practices for remeshing in ZBrush, a powerful software for digital sculpting and painting.

1 Why remesh?

Remeshing can have many benefits for your digital sculpture, such as reducing the polygon count, optimizing the UV layout, creating a more uniform distribution of polygons, improving the sculpting and painting workflow, and preparing the model for other applications or purposes. Remeshing can also help you fix some common issues, such as stretched or distorted polygons, holes or gaps in the mesh, or unwanted seams or artifacts.

When creating a 3D sculpt in programs such as Blender, ZBrush, or Mudbox, the final result will usually have an extremely high polycount. Which means your CPU might not respond accordingly due to how high it is. But mainly the high and usually messy poly count is not suitable for rigging and animation purposes which is why 3D artist usually retopologize when they are finished with their 3D sculpt.

2 When to remesh?

Remeshing can be done at any stage of your sculpting process, but it is usually recommended to do it before you add fine details or textures to your model. This way, you can preserve the overall shape and volume of your sculpture, while creating a better base for further refinement. Remeshing can also be done after you finish your sculpture, if you want to optimize it for rendering, animation, or 3D printing.

You should retopologize when you need to rig and animate said sculpt. When you are done creating new low and clean topology, you can bake your high poly mesh details onto your low poly mesh using either Maya, xNormal, or Substance Painter.

3 How to remesh?

ZBrush offers several tools and options for remeshing, such as DynaMesh, ZRemesher, Decimation Master, and UV Master. Each of these tools has its own advantages and disadvantages, depending on your goals and preferences. For example, DynaMesh is great for creating a quick and easy remesh, but it can also create a high polygon count and lose some details. ZRemesher is more advanced and can create a more accurate and efficient remesh, but it can also take more time and require more adjustments. Decimation Master is useful for reducing the polygon count without losing details, but it can also create a messy and irregular topology. UV Master is helpful for creating a UV layout for your remesh, but it can also create some distortion or overlapping.

You can either use the Remesh function in Autodesk Maya, which should give you clean quad topology or based on your setting preferences. Or you can mainly use the quad draw tool to retopology. ZBrush also has various of functions to help out with remeshing. ZBrush uses functions such as ZRemesher and DecimationMaster. Decimation Master helps preserve the detail you added to your high poly sculpt while lowering the topology. ZRemesher lowers your poly count will making sure the topology is clean.

4 What to avoid?

Remeshing can introduce some problems and mistakes that you should avoid or fix. It's important to not remesh too often or too late, as this can slow down your workflow and make it harder to preserve details and textures. Additionally, you should always have a plan and a purpose for remeshing, such as improving performance, quality, or functionality. When remeshing, make sure to check and test the results for any holes, gaps, seams, artifacts, distortion, or loss of details. If any are found, be sure to fix them before continuing with your sculpting or painting process, or exporting your model.

5 How to improve?

Remeshing your sculpture is an important process to get the most out of your digital sculpting. To help you create a better remesh, there are some tips and tricks you can use. Depending on your needs and preferences, you should choose the right tool and settings for your remesh. Experimenting with different options and parameters can also help you find the best balance between speed, accuracy, and efficiency. Additionally, masking and polygroups can be used to control your remesh, while projection and morph targets can help restore any details or volume that might be lost during the remeshing process. By following these best practices for remeshing in ZBrush, you can create a more effective remesh and improve your workflow and results.
