Discover how to create creature fur from scratch in Maya using XGen and Arnold with Creature FX Artist Bruno Tornisielo. This 2.5-hour workshop details Bruno’s process for crafting believable hair and fur, starting with a simple sphere to demonstrate XGen's fundamental tools and principles. Bruno reveals all the important tools needed to create curves and modifiers and discusses how to create clumps, cuts, noise, and curls.


With the foundations covered, Bruno covers the importance of separating the groom into layers to gain complete control over the groom. He shares the entire process for creating all the guides and layers for the full groom and demonstrates the modifiers required for each layer before walking through his light rig and shaders. Bruno also details how to paint maps using ZBrush as an added bonus. The workflow follows through to the final render in Arnold and shows how to create an interactive groom for your portfolio.


This workshop is designed for artists looking to learn the basics of XGen as well as those interested in learning how to create realistic animal and creature grooms. This tutorial is packed with useful grooming tips and provides a comprehensive overview of Bruno’s production workflow, as used for creating realistic creature grooms for feature films.


Bruno has provided his XGen Expressions .txt file as a downloadable resource with this workshop, which is available to subscribers.

01Introduction to Maya XGenFree

This introductory XGen lesson establishes the fundamental workflow for creating hair and grooming in Maya, emphasizing proper technical setup before creative work begins. Bruno’s preferred approach focuses on guide-based grooming with curve manipulation rather than interactive grooming tools, providing a solid foundation for beginners. While XGen offers many tools and options, mastering the basics of project setup, UV requirements, guide creation, and essential modifiers is crucial before exploring more advanced techniques in future lessons.

Duration: 23m 11s

Introduction to Maya XGen
02Head Curves & Effects

This lesson establishes the foundational workflow for creating realistic fur in XGen through an iterative, non-linear process. Bruno shows that achieving natural-looking results requires constant refinement. This includes adding curves, adjusting clumps, painting masks, and generating variations repeatedly throughout the project. While the technical steps are methodical, success depends on artistic judgment and patience rather than following a strict linear process.

03Chest Curves & Effects

This lesson emphasizes that creating realistic fur is an iterative process requiring patience and constant refinement. The key to success lies in understanding how curve interpolation works, maintaining consistency across layers with standardized parameters, and using proper masking techniques for seamless integration. Bruno teaches that, while issues like geometry penetration are common, they can be easily resolved by strategically adding curves and reshaping them to follow the character's natural form and flow.

04Tail Curves & Effects

This lesson emphasizes that creating realistic digital fur is an iterative process requiring attention to both overall flow and integration details. Bruno's key to success lies in layering multiple effects (noise, clumping, curl) with varying parameters and repeatedly adjusting transitions between different body sections until a seamless, natural appearance is achieved. While procedural tools are helpful, manual refinement and integration of problem-solving are essential steps in the grooming workflow.

05Legs Curves & Effects

This lesson emphasizes that creating realistic fur in Maya is an iterative process requiring patience and constant refinement. Bruno's key focus is on how fur systems require recalculating effects whenever curves are modified, and on achieving natural-looking results by carefully managing curve density, flow direction, and multiple layers of clumping effects to create depth and realism in the final fur appearance.

06Fur Refinement

This lesson illustrates the iterative and detail-oriented nature of digital fur creation, emphasizing that achieving natural-looking results requires constant testing, adjustment, and refinement of multiple parameters. Bruno demonstrates that successful fur effects rely on finding the right balance between technical settings (such as CV count and curl values) and artistic judgment, often requiring multiple attempts to achieve the desired look. The unexpected blend of the original scaled dinosaur design with fur elements shows how creative accidents can lead to unique and interesting results.

07Tail Fur: Tip Curves & Effects

This lesson emphasizes that creating realistic fur grooming is an iterative refinement process requiring constant adjustment and testing. Bruno demonstrates that achieving natural-looking results involves layering multiple effects (clumping, noise, cutting, masking) and being willing to continually revise settings until the desired appearance is achieved. The work shown here is preparatory, with the understanding that further refinements will be necessary once texturing begins, especially when viewing renders, where issues become more clearly visible.

08Lighting Set Up & Refinement

This lesson provides practical insight into professional 3D character-finishing workflows, emphasizing the iterative nature of grooming and lighting. Bruno demonstrates that achieving quality results requires constant refinement, such as reshaping curves, updating masks, and troubleshooting render issues, while maintaining efficiency by using the minimum necessary curves for simulation performance. Matching lighting environments across software packages ensures consistency throughout the production pipeline.

09Flyaway Curves & Effects

Creating a flyaway hair layer is a straightforward but impactful technique for adding realism to 3D character fur and hair. By duplicating existing curves, applying low-density settings, and using selective masking with subtle styling effects, artists can achieve natural-looking stray hairs that enhance the overall detail of their models. This method is applicable to various animal and character designs.

10ZBrush Quick Look at Texturing Tools

This lesson serves as a focused primer on ZBrush's texture-painting capabilities rather than a comprehensive introduction to the software. Bruno emphasizes that artists can follow other workshops for more general ZBrush guidance, as this lesson specifically covers the Polypaint texturing workflow demonstrated. His streamlined approach helps artists quickly understand the essential tools for upcoming lessons without being overwhelmed by ZBrush's extensive feature set.

11Creating Textures & Shaders

This final lesson emphasizes the importance of experimentation and iteration when creating fur textures and shaders. Bruno demonstrates that achieving realistic results requires balancing melanin, diffuse color, roughness, and transmission tint while constantly testing renders to evaluate the outcome. By creating multiple texture variations and fine-tuning shader properties through systematic adjustments, artists can achieve professional-looking fur that maintains both artistic vision and natural realism.
