Create massive animated crowds in seconds using procedural character instancing and randomized animation offsets for concerts, stadiums, events, and custom large crowd simulations.

File Types (supported programs):

Unreal Engine 5.4.4+

10 textured animated characters spawner (VAT + HDIM pipeline) with seats.

The free AnimToTexture plugin should be enabled!

1. Check for init_unreal.py script installed at: <YourProject>/Content/Python/init_unreal.py using Windows Explorer.

2. Drag 3 Blueprints from the CrowdGen folder into the level.

3. BP_SeatArea - adjust borders of the crowd using prepared splines.

4. Set up your crowd using BP_CrowdGen in real time.

5. BP_LookAtTarget - set the look-at target for all crowds.

Full Tutorial for UE: https://youtu.be/4Qjr3puO4bE

Blender 5.0.1+

Install add-on procedural_crowd_generator.py (Blender → Edit → Preferences → Add-ons → Install) and start populate:

1. Select the surface.

2. Set rows and seats per row.

3. Pick 1-10 unique characters (armatures) from the scene (or use your own FBX with animation).

4. Press Build Crowd → the crowd appears on the surface.

5. Optionally, randomise animation, offsets, rotation, colors, or rebuild. Move or delete individual meshes.

3ds Max 2022+ (free tyFlow plugin required - v0.16134 or newer)

1. Merge ProceduralCrowdGenerator group from the Demo scene into your project.

2. Set the surface, character count, and other options.

Inside the FBX folder, you'll find 10 demo animated mid-poly FBX files with different animation types.

Procedural Crowd Generator is a powerful tool designed to instantly populate any surface with fully animated crowd characters. Built for stadiums, concerts, arenas, and cinematic environments, it automates the entire process of crowd layout, instancing, and animation variation. Instead of manually placing and managing hundreds or thousands of characters, this tool lets you generate a complete animated crowd with a single click.

This Stadium Crowd Tool includes a version for Unreal Engine 5. Create dense, animated audiences along custom spline seat areas using Hierarchical Instanced Static Meshes (HISM) and VAT animation. Control character variants, weights, density, chairs, look-at targets, phase offset, camera flash effects, and shadows. Includes one-click Bake Crowd to produce independent, movable crowd actors. Optimized for large stadiums, sports arenas, and live events. Easy Blueprint workflow with Python backend.

Crowd System Core Features

• Procedural seating grid generation on any mesh surface

• Access to each mesh in Blender and 3ds max version (move, scale, rotate, or delete if you need)

• Automatic crowd instancing

• Multi-character support (mix and randomize different avatars)

• NLA-based animation system with per-instance offsets

• Fully randomized motion timing (no synchronized crowd movement)

• Surface raycast placement (accurate seat-to-mesh projection)

• Optional character rotation controls (face center / custom direction)

• Scale inheritance from source characters (Mixamo-friendly)

• Built-in seat preview system (debug / layout visualization)

• Collection-based crowd organization (non-destructive workflow)

• One-click crowd rebuild and clear system

Use Cases

🏟 Stadium & Sports Visualization

Generate realistic audience crowds for football, basketball, esports arenas, and stadium flythrough shots.

🎤 Concert & Festival Scenes

Populate massive concert venues with animated spectators for cinematic lighting and atmosphere shots.

🎬 Film & VFX Previsualization

Quickly block out crowd density and motion for pre-production or layout stages in VFX pipelines.

🎮 Game Environment Design

Create background crowds for stadium levels, city events, or cutscene environments.

🏗 Architectural Visualization

Bring static renders to life by adding scale, occupancy, and realism to large venues.
