Trying to steal Vray's thunder.
Dave Stewart, a 3D artist with 20 years of experience in high-end 3D, match moving and compositing, is a true guru of Houdini. The artist has been sharing peculiar and amazing simulations for years and his art is something that can make you want to learn Houdini.
Let’s take a look at some of his videos:
Mucking about with a number of workflows with these: custom wind fields, advected Cd fields, rest field displacement, particles that advect from Pyro and also add density/Cd/vel, adding lightning arcs post-sim, and seeing how many advected points my system could handle (360 million with 32gb ram).
Warning – ugly render ahead!! 🙂 Very draft, no refraction or fluid interior volume. Simmed/rendered simultaneously on a single machine overnight.
Testing a setup to dynamically erode a collision volume with a FLIP sim. Seems to work quite reliably so far, and looks really cool!
Also had fun setting up a quick wet map SOP, and figuring out how to shade the underlying strata of the eroded object based on it’s distance from the original surface. VDB’s rock!!!
Here’s a simple example .hip file showing the erosion setup.

Having some fun with stacked POP solvers, based on the great ideas in this ODForce thread.
Featuring Sid, the invisible displaced sphere! 😉
Viscosity based on point age, remapped with a ramp in a POP VOP. Rendered with Mantra PBR.
Hardening speed is exaggerated to be sure, was trying to preserve all the nice folds that form initially.
