In this 5-hour workshop, Alexander Lee teaches his revolutionary animation workflow using ZBrush. Each frame is sculpted individually, resulting in a handcrafted final shot. This workshop covers the entire pipeline, including character setup in ZBrush and Maya, frame management with UltraClay, frame-by-frame animation in ZBrush, and final lighting, rendering, and compositing in Maya and Blender.

Alexander breaks down his thought process for creative problem-solving, from initial concept and inspiration to final renders. Artists will learn tips and techniques spanning character sculpting, rig setup, keyframe animation, frame sculpting, lighting and rendering, and compositing. Drawing from his expertise as a senior technical artist working in the video game and visual effects industries, he also shares his thoughts on creating production-ready animation tools to improve workflow efficiency.

This workshop is intended for intermediate- to advanced-level artists, particularly those familiar with sculpture and animation workflows. Prior experience is recommended in both ZBrush and an animation software of choice. While Maya is used for this workshop, and the provided tools are Maya-specific, the fundamental concepts can be applied in other packages such as Blender or Houdini. Beginner artists will also find value in the early chapters, where a simple animation workflow is presented using only a limited set of features already present in ZBrush.

Software used for this project includes ZBrush, Maya, and Blender. Alexander's proprietary UltraClay animation tool is also provided to all Gnomon Workshop subscribers, along with a detailed installation tutorial. Finally, a custom ZBrush menu is also included in the Project Files, providing easy access to the most commonly used ZBrush features.

01ZBrush Setup & Custom MenuFree

In this first lesson, Alexander Lee discusses setting up custom menus in ZBrush, which will assist the process both for initial character sculpting and final frame sculpting. The "quick menu" provides easy access to common functions such as brush settings, automasking, mesh modification options, Sculptris, DynaMesh, and more. He also shows how to set up a custom menu for selecting a subset of brushes, such as Snakehook, Inflate, DamStandard, and ClayBuildup.

Duration: 20m 47s

ZBrush Setup & Custom Menu
02Basic Claymation in ZBrush

In lesson 2, Alexander covers creating a basic Claymation in ZBrush, using the principle of Subtools as frames. Each frame of animation is a separate mesh. He shows how to switch between them using hotkeys to move up and down the Subtool stack. He also discusses using Sculptris in an animation context, and how to append previously completed sculpts to your animation Subtool stack.

03ZBrush Materials & PolyPaint Setup

In lesson 3, Alexander provides an overview of his material and color texture pipeline. Using PolyPaint in ZBrush, he shows how to set up material and lighting settings to accurately match the final rendering color space in Maya. He then demonstrates direct one-to-one visual comparisons to ensure that the colors painted in ZBrush will be representative of the final animation result.

04Scene Blocking & Character Sculpting

In lesson 4, Alexander covers the thought process when designing a new animated shot. He shows how to block out initial poses using character rigs in Maya, and how to test out some of the simple transitions and movement. Then he sculpts and PolyPaints the main character, using existing basemeshes from previous projects. Finally, he demonstrates how to set up a character rig in Maya using the RapidRig Modular auto-rigging tool.

05Reference Tips

In lesson 5, Alexander discusses the usage of PureRef for image reference, the coverage to look for when finding photo versus artwork reference, and techniques for avoiding AI-generated images in Google search and other image search engines. He also discusses the role of reference versus imagination when creating an animated shot from scratch.

06Hand Sculpting & Rigging

In lesson 6, Alexander covers the sculpting process for the large hands in the animated shot. Starting from an existing hand sculpt, he teaches how to change proportions and re-sculpt secondary forms before tackling a final pass for tertiary forms and details, and the Polypaint coloring. Finally, he demonstrates how to rig the final hand mesh in Maya using RapidRig Modular.

07Animation in Maya: Pass 1

Lesson 7 dives into the animation process in Maya, starting with blocking poses and then beginning the straight-ahead animation process. Alexander demonstrates how to set up multiple camera views, including one with the final render perspective. He shows how animating “to-camera” allows artists to work efficiently, by ignoring viewpoints that will not be seen in the final result.

08Animation in Maya: Pass 2

Lesson 8 continues the animation process in Maya, adding inbetweens, fixing arcs, retiming, and polishing. Alexander also teaches how to add pose-specific corrective blendshapes. He shows how correcting broken deformations at this stage helps to eliminate repetitive frame-sculpting in ZBrush at the next stage. He then uses the Maya Shape Editor to add the blendshapes, and set keyframes on the envelope for each target.

09ZBrush Frame Sculpting: Pass 1

In this ninth lesson, Alexander covers the first pass of ZBrush frame sculpting. First, the animated meshes are exported from Maya using his proprietary pipeline tool UltraClay. He then shows how they are imported into ZBrush for the sculpting process to begin. In the first stage, he shows how to set up Polygroups for the independent objects before moving the major forms into place using the Gizmo and SnakeHook brush.

10ZBrush Frame Sculpting: Pass 2

In this tenth lesson, Alexander continues the frame-sculpting process in ZBrush. He shows how to use tools like Gizmo Union and Sculptris Pro to create smooth transitions between objects, and how to refine the animation using a variety of smoothing and remeshing techniques. He also demonstrates how to use UltraClay to import the sculpted animation frames into Maya to check timing and spacing with incremental playblasts.

11Lighting, Rendering & Compositing

In this final lesson, Alexander concludes his claymation workflow. With the final sculpted frames imported into Maya, he shows how to set up the material and rendering settings. He also discusses his lighting set up, providing techniques to help artists control the spread of light to focus attention on the central action in the animation. Lastly, he shows how to render the animation and composite the image sequence in Blender.

In this lesson, he discusses installation and setup, tips and tricks for best performance, and covers a full export > frame sculpt > import demo in real-time.

Skills Covered

Who’s this Workshop for?

This workshop is intended for intermediate to advanced artists comfortable with animation and sculpting workflows. Proficiency in both ZBrush and Maya is recommended, but Maya can be replaced with other animation software, such as Blender or Houdini. 


Artists of any level can jump straight into basic animation in ZBrush using the steps presented in the early chapters. Alexander teaches the same basic technique in an introductory ZBrush college class, supporting students to produce detailed animations with no prior digital sculpting experience.
