Production Setup: Audioreactive Particles Using Vellum & POPs (Free Houdini Tutorial)

Support us on Patreon: You wanted to know how to set up something similar to Daniel Sierra’s “Oscillate” () in Houdini. So in this tutorial we’ll walk you through the steps necessary to not only create an audioreactive Vellum simulation but also add secondary particles into that simulation and create further detail through VEX. Lastly we’ll also talk about setting this up for rendering using Octane. 00:00 - Intro 00:34 - Breaking Down The Effect 01:33 - Line Setup 02:38 - Importing Audio Using CHOPs 06:07 - Using The Audio Signal To Animate Points 08:27 - Setting Up The Vellum Simulation 09:22 - Additional Lines 11:42 - Emitting Particles From The Main Line 14:33 - Tweaking The Particle System (Turbulence, Particle Life, Initial Velocity) 16:48 - Particle Scale Over Life 19:16 - Setting Up The Particle’s Geometry 22:52 - Secondary Elements: Velocity Lines 25:43 - Secondary Elements: Lifetime Arcs -
