Sand castle collapse 3D animation VFX

A sand castle collapsing with Houdini. Just testing Houdini grain sim and mantra BPR rendering. I used 2 animated spheres to wake up the particles. Render was only between 2 to 5 minutes a frame with mantra BPR for 5.2 million particles. It took around 3 minutes a frame for simulation (5 hours total).


Morve Verte : Sticky Green Goo with some variable break treshold and variable clumping

A grain sim in Houdini meshed with VDB and loaded in 3ds Max to render with V-Ray. I used an attribute vop after the grainsource to assign a noise to the parm_threshhold point attribute (yes threshhold with 2 “h”…) (which control the break treshold) and also to the attraction weight point attribute (which controls the clumping).
