You wanted to know how to set up something similar to Daniel Sierra’s “Oscillate” (https://vimeo.com/65475425) 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 – Theory
28:11 – Secondary Elements: Lifetime Arcs – Implementation
32:50 – Secondary Elements: Setting Color & Width
34:35 – Setting Up Rendering In Octane
42:04 – Recap
42:58 – Infamous Last Words
