In this Houdini tutorial, we’ll build a necklace simulation using Vellum, then polish it with post steps for a clean final result. You’ll see a practical workflow for getting believable draping, stable collisions, and an easy-to-iterate setup. Great for character accessories, chains, and jewellery-style sims.


What you’ll learn :

- Setting up the necklace/chain geometry and guides

- Vellum sim workflow for draping and settling

- Pin/attach methods to connect multiple necklaces.
