ZBrush Tools for Character Artists

Digital Sculpting: ZBrush is a powerful digital sculpting application that allows artists to create detailed 3D characters using various tools and techniques.
Polygonal Modeling: ZBrush's initial approach is often utilizing base meshes, which may be converted to other formats for further use.
Direct Modeling: ZBrush is primarily known as a direct sculpting tool, which involves sculpting directly on the surface of the model. This direct manipulation allows for high degrees of detail and organic forms.
Clay Buildup: This technique involves layering on digital 'clay' materials for incremental creation and refinement of shape.
Subdivision Surfaces (SubD): ZBrush utilizes SubD (Subdivision Surface) modeling, which enables a smooth, editable surface that allows for highly detailed and organic modeling workflows. This avoids problems seen in polygonal modeling.

Brush Tools: ZBrush offers a diverse range of brushes, each with unique sculpting capabilities. Artists can add, subtract, and refine sculpted forms with precision and ease.
Standard Brushes: Many brushes serve basic shapes. These often have variations that modify brush behavior -- strength, size/radius, etc.
Altered/Advanced Brushes: Certain brushes like the Clay Buildup brush provide smooth results. Other brushes are designed for specific shapes or areas (e.g., extruding elements)
Draw: Basic brush capable of creating basic lines, and shapes in the medium
Claybuildup: Creates smooth, organic shapes. Ideal for creating large, smoothly flowing regions like the arms and torso of a character's body.
Pinch: Allows for the deformation and shifting of an area to create the effect seen in the pinching or pulling of clay. It is a good tool to define joints and other areas of the 3D model.
Flatten: The Flatten tool is a versatile tool for creating sharp, flat surfaces such as the edges of clothes or the contours of a character's body and other parts that require more definition.
Standard Brush: Generic brush that allows for the removal and addition of smaller, detailed parts. It can be difficult to control, so it is often avoided.
Inflate: This tool gently pushes or pulls a region apart on the 3D model.
Erase: Precisely removes sections of the digital clay, enabling easy sculpting.

Dynamic Topology: ZBrush's SubD system allows for the modification of sculpt meshes without affecting the structure at the base mesh. This permits for organic and detail-rich shapes.
Sculpt: The sculpting feature allows for detailed detailing, including wrinkles, folds, curves, creases and organic imperfections that are integral to realistic depictions.
Altering Existing Meshes: Often, artists improve on a pre-existing mesh or refine an existing 3D model.
Working with Layers: ZBrush's layer system allows for non-destructive sculpting. Multiple layers allow different elements to be sculpted independently and combined in various ways for flexibility.
Polygroups: Artists use Polygroups to manage and target specific areas of the sculpt for different brushes and techniques.
Working with Brushes in Combination: Characters are rarely sculpted purely with one tool, requiring a combination of brushes and methods.

Hard Surface Sculpting: Specialized brushes and techniques can be used to sculpt and create sharp edges and forms found in machines or robotic characters.
Adding details: Many techniques and tools allow for smooth blends of elements, creation of intricate details, and more complex elements like cloth simulation or fur generation to improve realism.
High-Resolution Sculpting: ZBrush enables the creation of very high resolution sculpting or detailed characters, and allows for detailing that cannot be matched with polygonal modeling.
Importing and Exporting: The software can easily import meshes and export them to a variety of common formats like .OBJ and .FBX, allowing for seamless integration with other 3D applications.
Texture Painting: Integrating texture painting with ZBrush's sculpting tools, allows artists to add detailed details, including color and highlights, for a more polished character model.
Using Polygroups and Masks: Artists frequently use polygroups to target different areas for specific brushes and techniques while maintaining more control over the sculpting process. Masks are a way to isolate sections without affecting the surrounding regions.

Early Stages: The initial stages of sculpting focus on the overall form, size, and proportions of the character.
Mid-Stages: Refine major form elements and add more detailed elements, focusing on the major features. Refinement of smaller details.
Final Stages: The process focuses on polishing areas, adjusting proportions, adding final details, and preparing them for presentation.
Iteration: A large portion of the ZBrush process involves many cycles of adding, removing, and refining elements and textures until the final aesthetic is achieved. The ability to quickly edit is key to this process.
