The Deformation palette provides a set of global transformation tools used to adjust the overall shape, scale, and proportions of a model without adding or sculpting surface detail. These operations affect the entire subtool or masked regions and are controlled through sliders, making them ideal for early block-in, proportional correction, and structural adjustments. Deformation tools are resolution-independent and predictable, allowing for clean transformations such as scaling, inflating, twisting, tapering, and bending. The Unify function is commonly used to center and uniformly scale a model so it fits correctly within ZBrush world space, ensuring consistent behavior across tools and workflows.

Primary Use Cases:

• Adjusting overall proportions during early block-in

• Correcting scale and positioning of imported meshes

• Applying controlled global transformations without surface distortion

• Preparing geometry for further sculpting and refinement

Sculpting Refined Form

AccuCurve modifies how a brush influences the surface by producing sharper, more defined edges with reduced falloff. This setting creates crisper and more intentional form transitions, making it especially effective for sculpting planes, hard breaks, and structural forms. AccuCurve is commonly used in combination with brushes such as Move, Clay, and Standard during the form refinement stage, rather than early block-in. By limiting softness in brush strokes, AccuCurve helps prevent mushy surfaces and maintains clean, readable shapes throughout the sculpt.

Primary Use Cases:

• Sharpening planes and edge transitions

• Refining structural forms without over-smoothing

• Maintaining crisp silhouettes during mid-to-late sculpt stages

• Improving clarity and readability of surface forms

The Pinch brush pulls surface points toward the center of the stroke, sharpening edges and tightening form transitions. It is commonly used to define creases, sharpen folds, and clean up plane changes, making it especially effective for wrinkles, hard edges, and stylized details. Pinch is best applied after primary and secondary forms are established, as excessive use can thin geometry or introduce surface artifacts. It is often paired with Smooth or Polish brushes to balance sharpness and maintain clean surface flow.

Primary Use Cases:

• Sharpening edges and tightening form transitions

• Defining creases, folds, and wrinkles

• Cleaning up intersections between planes

• Refining stylized or high-contrast surface detail.

Adjust Last allows you to modify the most recent brush stroke without undoing the action. It enables post-stroke adjustments to size, intensity, and depth, making it ideal for fine-tuning strokes that are nearly correct. Adjust Last is accessed through Stroke ▸ Replay Last ▸ Adjust Last and applies only to the last action performed. Once a new stroke or operation is executed, the adjustment option is no longer available, making this tool most effective for quick, immediate refinements.

Primary Use Cases:

• Fine-tuning brush strokes without undoing

• Correcting intensity or depth after a stroke is applied

• Improving precision during detail refinement

• Maintaining workflow efficiency during sculpting

Replay Last repeats the most recent brush stroke or action exactly as it was originally performed. This tool is useful for building consistent, repeatable detail without manually recreating the same stroke. Replay Last is accessed through Stroke ▸ Replay Last and can be triggered multiple times to stack identical results. It works best for patterns, wrinkles, and controlled incremental buildup, and the stored action is replaced as soon as a new stroke or operation is performed.

Primary Use Cases:

• Repeating consistent surface detail

• Building patterns or rhythmic forms

• Speeding up incremental sculpting workflows

• Maintaining uniformity across repeated elements

Depth controls how far a brush stroke pushes into or pulls out of the surface along the camera’s view direction. It directly affects how strongly a brush adds or subtracts volume, with higher values producing deeper, more pronounced strokes and lower values creating subtler effects. Depth is especially important when using Standard, Clay, and Inflate-type brushes, where volume control is critical. It can be adjusted through the Brush ▸ Depth menu or via brush intensity, helping artists avoid over-sculpting and maintain clear, readable forms.

Primary Use Cases:

• Controlling how strongly brushes add or remove volume

• Preventing over-sculpting during form development

• Fine-tuning stroke intensity for subtle detail work

• Maintaining readable form transitions and surface clarity

Tool and Brush Masking use masks to control which areas of a model are affected during sculpting and transformation. Tool Masking protects specific regions of a mesh from edits, while Brush Masking modifies how an individual brush interacts with the surface. Masks are commonly created by painting them directly, generating them from polygroups, or using selection tools, allowing artists to isolate areas, control deformations, and focus detail work. Masked regions remain unaffected by sculpting or deformation tools, enabling clean, precise edits without damaging surrounding forms.

Primary Use Cases:

• Isolating areas for focused sculpting or deformation

• Protecting existing detail during refinement

• Controlling brush influence on complex forms

• Making clean, non-destructive edits to a model

Polygroups divide a model into colored sections that help organize and control geometry within a sculpt. They make it easier to select, mask, hide, or isolate specific parts of a mesh, and many ZBrush tools can operate by polygroup for cleaner, more controlled edits. Polygroups are commonly used to separate hard-surface components, limbs, and distinct forms, and are essential for workflows such as ZModeler, Panel Loops, and masking. By breaking complex models into logical sections, polygroups help keep projects organized and manageable.

Primary Use Cases:

• Organizing complex geometry into manageable sections

• Isolating parts of a model for sculpting or editing

• Enabling polygroup-based tools and workflows

• Supporting hard-surface modeling and paneling operations

An Image Plane allows a reference image to be displayed directly within the ZBrush viewport for visual guidance while sculpting. It is commonly used to match proportions, anatomy, and silhouettes during form development. Image Planes can be positioned on the front, side, or top views of a model and do not affect the geometry in any way. Because they are reference-only, Image Planes help maintain accuracy and consistency throughout the sculpting process.

Primary Use Cases:

• Matching proportions and anatomical landmarks

• Aligning silhouettes to reference images

• Maintaining accuracy during block-in and refinement

• Providing visual guidance without affecting geometry

See-Through allows you to view internal or hidden geometry by making the surface of a model visually transparent. This view-only feature is useful for aligning forms, checking symmetry, and positioning internal structures without modifying the mesh. See-Through can be toggled on and off to quickly inspect spatial relationships between parts, making it an effective tool for accurate placement and proportion checks during sculpting.

Primary Use Cases:

• Inspecting internal or overlapping geometry

• Aligning forms and checking symmetry

• Positioning internal structures or components

• Verifying proportions without altering the mesh

The XTractor Brush samples surface detail from one area of a model and transfers it to another during sculpting. It works by copying the surface height and form under the cursor and reapplying that detail as you stroke, allowing for consistent repetition of textures, wrinkles, and surface patterns. The XTractor Brush does not copy color, only sculpted form, and works best when applied to areas with similar curvature and scale. This brush is commonly used to speed up detailing workflows without manually recreating the same surface detail.

Primary Use Cases:

• Repeating surface textures and patterns

• Duplicating wrinkles or sculpted details

• Maintaining consistency across similar areas

• Speeding up detail work without resculpting

Contrast Delta

Contrast Delta increases the difference between high and low points on a surface, sharpening existing detail by pushing peaks higher and valleys deeper. It enhances texture and surface definition without adding new forms, making it ideal for strengthening detail that is already present. Contrast Delta works best during the late stages of refinement and should be used lightly, as excessive values can create harsh or noisy surfaces.

Primary Use Cases:

• Enhancing existing surface detail

• Increasing contrast in textures and fine forms

• Strengthening sculpted details without adding geometry

• Final pass refinement of surface definition
