Horde Add-On: Procedural Crowd Tools is a crowd system for Blender that adds customizable crowds of animated 3D characters to any scene. It's built on two of Blender's crowd approaches — geometry nodes and boids — and its UI panel was designed in collaboration with Carlos Barreto. It serves 3D renders and live-action VFX alike.
Setup runs in four steps: choose a character genre, pick an animation mode, select a system type, then add or draw the crowd directly into the scene through the UI panel. Horde ships with four character sets — Human Professional, Human Casual, Zombie Bare, and Zombie Clothed — created by artist Elliot Feys, each working with Walk, Run, and Static animation modes. The geometry node system handles precision placement, while boids produce organic emergent crowd behavior.
Because Horde builds its parameters on Blender's native geometry node and boid particle systems, crowd setups stay fully customizable afterward, both through the panel and inside Blender itself, with no proprietary formats or locked settings. Assets are optimized for Cycles and EEVEE, and the add-on scales to hundreds of characters.
