Legendary Threads by REQUIRES

This course teaches you how to build procedural 3D knitting inside Houdini. You’ll go from basic thread logic to wrapping knit around products and animating it for shots. No hand-modeling loops—just smart, repeatable setups.

🎯 What you’ll learn

• Build procedural thread and yarn systems from scratch
• Wrap knitted geometry onto any product surface
• Animate knit patterns for dynamic shots
• Create high-resolution versions for final renders

✅ Requirements

• Skills: Intermediate knowledge of Houdini, familiarity with VEX and attribute wrangles
• Tools: 3-button mouse
• Hardware: 16 Core 3.4GHz CPU, 64GB RAM or more; 24GB VRAM GPU recommended for Karma XPU rendering

📝 Description

This isn’t a generic modeling course. It’s a deep dive into procedural knitting—building thread loops, yarn systems, and fabric patterns that wrap onto any 3D surface. You’ll start with the fundamentals of thread generation, then move straight into projecting that logic onto product geometry.

The real power comes in the animation module. You’ll set up growth animations that make the knit appear to weave itself onto the object, perfect for product reveals or VFX shots. The course also covers upresing your low-res sims into high-detail renders, using Karma XPU for final output.

Project files are included as files for Houdini Indie. The workflow is built for version 20.0.506, but the core concepts translate to newer builds. Expect to spend time tweaking parameters—this is about understanding the system, not just copying steps.

🧑‍🎓 Who this course is for

• Houdini artists looking to add procedural fabric techniques to their toolkit
• Technical directors and FX artists needing realistic knit for product visualization
• Intermediate users who want to move beyond basic simulations into custom geometry generation

🏁 Final Result

• A fully procedural knitted fabric system that can be applied to any product geometry
• An animated knit growth sequence ready for final rendering in Karma XPU
