The following are features for Mudbox 2018.2 update.
Tessellation
A new Tessellation option in the Sculpting Tools properties adapts to your sculpting process by adding polygons (triangles) to your mesh as you sculpt. This way, you no longer need to create a high-density base mesh when starting; you can now infinitely build up a low-poly base shape in Mudbox as you go.
Activate the Tessellate check box in the Sculpting Tools properties of any sculpting brush that adds extra surface area to a model, for example, Grab and Bulge.
Once activated for a brush, Mudbox intuitively increases the polygon count as you work, creating high-density meshes as you need them. The default setting, Screen Pixels, lets you increase the model's resolution as you zoom in. (You can also reduce the mesh resolution this way with the Reduce tool, defined below.)
- Your mesh needs to be triangulated to use Tessellation. This means it can't have any sculpt layers, subdivision levels, non-manifold edges, or UVs. Because of this, it is a good idea to use this technique early in your workflow (that is, before texturing). If you use an unsuitable mesh, Mudbox automatically creates an editable copy of it to work on, or you can also do this yourself by selecting .
- A limitation exists where Dynamic Tessellation deletes weights.

New sculpt tools
Three new tools, Remesh, Reduce, and Refine, have been added to the Mudbox Sculpt Tools tray to let you build up or cut down resolution by adding or removing polygons (triangles) to your mesh.
Remesh is a high-level tool to let you quickly increase or decrease the mesh as you work, while the Refine and Reduce tools more purpose-built sub-tools for specific mesh operations. For example, use the Remesh Tool when you want to move back and forth adding and subtracting to the resolution of you mesh as you work, but if you know you don't want to decrease your mesh resolution, use the Refine tool. Similarly, use the Reduce tool when the only thing you want to do is remove polygons from the mesh.
- Remesh
- The
Remesh tool reacts to how close you are to the mesh. If you are zoomed in on the model, it will increase the resolution of the mesh surface to let you add detail in specific areas. If you zoom out, and use
Remesh, the polygon density is reduced.
- To only increase or decrease resolution, use the Refine or Reduce tools.
- Refine
- Use the
Refine tool to increase the resolution of the mesh. This increases the resolution of your mesh so that you can work in greater detail.
- Reduce
- Use the Reduce tool to lessen the resolution of the mesh. This lets you decrease the density of the mesh in areas that do not need heavy detail. Reduction is common in places where there aren't a lot of geometry features or complexity, so you can reduce polys in one area in order to allow for a higher poly count elsewhere.

Edge Bleed for Map Extraction
There is a now a new Custom setting for Edge Bleed in the Extract Texture Maps window Image Properties area that lets you set your own default Edge Bleed value when doing Map Extractions. The default Edge Bleed setting, Global, continues the legacy behavior, which uses the Edge Bleed value specified in the Paint Preferences.
Gamma Correct Blending
A new option, Gamma Correct Blending, has been added to the Advanced section of the Paint Brush Properties.
When you turn on this option, the texture painting blend colors before gamma correction, eliminating dark edges that appear where colors intersect, for example, when painting green over red.
When this option is off (the default), the legacy behavior is used and edges between overlapping paint is dark. If the option is turned on, instead of a dark area, the overlap between red and green displays as yellow.
High DPI Monitors
If you are using Windows and your monitor is set to a resolution higher than 1920 x 1080 (2K), use the regular Mudbox shortcut only the first time you license the software (or need to sign in again). After that, always use the Mudbox High DPI shortcut. This is necessary because Mudbox scaling is currently incompatible with the licensing software.
