Two procedural modeling projects in Houdini: a jellyfish whose bell, arms, veins, organs and tentacles each come out of a node network, and a digital asset that stacks floors into a building.
BellA profile curve revolved around the y-axis, shaped by two Bend nodes and animated with keyframes
ArmsCloth simulation: Vellum constraints, then the Vellum solver
VeinsThe bell is remeshed into triangles, Find Shortest Path grows the branches, and they are resampled, fused and smoothed
OrgansA Bézier curve swept into a tube, rotated and copied, with Mountain noise for variation
TentaclesLines copied onto points of the rim and simulated with Vellum, the way hair is
Building generator
A Houdini Digital Asset that stacks boxes into floors and adds pillars, borders, and supports under overhangs. Windows, doors and balconies have width and height controls, and an alternative set of models can be switched in with one click.
The setup follows Simon Houdini’s procedural house tutorial. The alternative door, balcony and window models come from Sketchfab and are credited in the repository.
