Stop Recooking Your Sims — Use the Labs File Cache Node | Node by Node

Wedging doesn't have to be a production. In this Node by Node, I'm walking through the Labs File Cache node — specifically how its built-in wedge index turns a slow, folder-juggling process into a one-click iteration machine. We're running this on a soil MPM simulation using a Drucker-Prager material model, wedging friction angle across three values to see how the material flow changes. The workflow itself transfers to anything — Pyro, RBD, Vellum. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ What you'll learn: → Labs File Cache vs. standard File Cache — what actually changes → Wedge Count, Wedge Index, and Load from Disk explained → Flipping between cached sims in real time with zero recook ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Node by Node is a series where I break down individual Houdini nodes — what they do, why they matter, and how to actually use them in a production context. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📬 The Briefing — my free weekly newsletter for VFX artists: https://bryanholt.media/briefing 🛒 Annotated .hip files and HDAs: https://bryanholt.media/store 💬 Join the Discord: https://discord.gg/Z6SHfbeMdR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ #Houdini #HoudiniFX #VFX
