Follow along to create a floating fantasy scene for Unreal Engine using Houdini, Mixamo, Photoshop, and Character Creator. The workflow, tools, and principles taught have been used by Senior VFX Artist Keagan Williams on videogame titles such as Marvel’s Midnight Suns.


The goal of this workshop is to guide you through the creation of the fantasy scene demonstrated by Keagan while also empowering you with the skills you need to efficiently, flexibly, and beautifully develop and express your own creative ideas.


Primarily aimed at beginner to mid-level artists, this workshop is ideal for those looking to create real-time VFX portfolio pieces, particularly those that go beyond basic particle systems. The scene demonstrated through this workshop features a central VFX element, and Keagan also touches on the worlds of Houdini’s KineFX and Vellum, as well as stylized hair, lighting, blueprints, and more. Some basic Houdini and Unreal Engine knowledge is recommended.


Tackling tricky VFX sequences involves an initial investment of time; however, you’ll discover that the techniques demonstrated will open you up to much greater creative freedom on your own projects.


You can follow along using the character demonstrated in this workshop; alternatively, you can create or use your own. When following along with this tutorial, we recommend downloading the (free) Mixamo characters and animations as referenced by Keagan. Additionally, Keagan has provided the files needed for almost everything else seen in the workshop.

01IntroductionFree

In this workshop, Keagan guides artists through creating a fantasy VFX scene while also teaching them how to develop and express their own creative ideas efficiently. The workshop’s flexible, non-linear structure and multiple reference projects are designed to support different skill levels and encourage independent creativity.

Duration: 3m 49s

Introduction
02Body, Clothing & Hair Setups

In this lesson, Keagan establishes fundamental principles for preparing characters for VFX simulation work in Houdini. The instructor demmonstrates that by focusing on clean, simple character models and learning to troubleshoot issues, like missing skinning data, intersecting geometry and improper collisions, artists can create efficient simulation-ready characters without getting lost in character design details.

03Bones, Simulations & Animations

In this lesson, Keagan demystifies the process of cloth simulation by presenting it as a logical series of steps rather than an overwhelming technical challenge. A major component of this is that effective simulation relies on proper organization and data flow, keeping elements separated, transferring attributes correctly and optimizing what actually needs to be calculated. By establishing this foundational workflow, artists can create a flexible pipeline that adapts to different characters and animations while maintaining good performance.

04Central VFX Element

In this lesson, Keagan encourages experimenting with simple shapes and procedural effects in Houdini, showing that not every VFX task needs to be overly technical; sometimes a quick, creative solution can produce impressive results. He also reviews pipeline options like VAT, Niagara, and Alembic, helping artists choose the workflow that best fits their specific project.

05Exporting, Importing & Debugging

In the lessons so far, Keagan has demonstrated a fast, flexible, and procedural approach to character animation, including realistic cloth and hair simulation. With patience and practice, artists can overcome technical challenges and gain a lot of creative freedom; benefiting from real-time feedback, no render times, and the ability to iterate quickly.

06Materials, Blueprints & Lights

In this lesson, Keagan shows how to balance visual quality with production practicality by using smart workarounds, like opacity masking for intersections and simplified material setups, instead of spending time on perfect but slow solutions. He also finalizes the character’s hair, applying a proper simulation and integrating it into Unreal Engine.

07Pipeline

Keagan showcases the full flexibility and stability of his node network in Houdini, now cleaned up and reorganized for ease of use. Focusing on the skeletal mesh integration and multiple simulation elements, he shows how starting simple and expanding gradually from base node systems produces more stable results.
