About Crowd Mixer

Crowd Mixer Overview

Crowd Mixer is a Blender add-on that simplifies creating and managing crowds in 3D scenes. It lets you build, customize, and place large groups of characters with flexible options for body parts, clothing, animations, and layouts — all in a non-destructive workflow.

The add-on includes tools for modular character setup, Mixamo animation integration, and detailed control over how crowds appear and move. You can arrange characters in grids, standing groups, or along curves, depending on your project.

To get started quickly, Crowd Mixer provides ready-made presets for common scenarios such as stadiums, streets, protests, and exhibitions. Select a preset, adjust it to fit your scene, and you’re ready to go.

Key Features.

• Modular Characters Assemble characters from interchangeable parts like head, body, clothing, and accessories — and randomize them for variety across your crowd.

• Animation from Mixamo Import FBX animations and categorize them into standing or walking groups. You can apply them to crowds based on the layout type with minimal setup.

• Ready-made Presets Crowd Mixer comes with a growing library of ready-made crowd presets, tailored for different environments. Just pick one and adjust it to your project.

  Presets include:

  Preset Name	Use Case
  SportsStadium (cheer/calm)	Seated audience with cheering or idle motion
  UrbanStreet	Street crowds, walking or standing
  Seminar	Indoor seated event like a talk or panel
  Exhibition	Casual groups for trade shows or gallery setups
  TransportStation	People walking or waiting in transportation hubs
  ProtestMarch	Moving groups with signs, for activism scenes
  ProtestStanding	Standing protest with dense formation
  Concert	Large audience facing a stage
  Beach	Relaxed crowd near a shoreline

  These presets save you time — you can drop them into your scene, make small adjustments, and you're ready to go.

• Three Crowd Types Each preset is based on one of these core layout systems: • Stadium – Uses curves to define seating layout for each tier. Each curve represents the first row of a tier, and curve points indicate seating section divisions. • Standing – Static or lightly randomized placement, good for lobbies or exhibitions • Flow Curve – Characters follow a path, perfect for movement or walking groups

• 3D Cursor Placement Use Blender's 3D cursor to place crowd objects exactly where you need them. Great for custom layout and precision in archviz or VFX.

• Geometry Nodes Integration Crowds are generated using node-based systems with sliders for control over density, spacing, randomness, and animation blending — all handled in the background.
