iCrowds – Advanced Crowd Simulation Tool for Blender
Bring life, scale, and realism to your scenes with iCrowds, a next-generation crowd simulation system designed for architectural visualization, urban planning, film production, and game development. iCrowds combines powerful static distribution systems with an advanced dynamic movement engine, giving you complete control over how crowds appear, behave, and interact inside your environments.
Whether you're building a stadium full of people, simulating pedestrians across a city, or generating natural crowd motion for animation—iCrowds delivers unmatched flexibility, performance, and ease of use.
Why iCrowds?
✔ Complete Crowd Ecosystem
iCrowds includes multiple systems that work together seamlessly—scattering agents on terrain, placing them inside venues, lining them along walkways, or animating them through dynamic paths.
✔ Static + Dynamic Control
Start with precise static placement using specialized distribution systems, then activate dynamic movement using a powerful physics-driven fluid engine that simulates walking, avoidance, attraction, and complex behaviors.
✔ Built for Real-World Applications
From massive stadiums to dense city streets, iCrowds is optimized for performance and scalability, making it suitable for everything from still renders to real-time workflows.
Core Systems Included
Static Distribution Systems
- On Ground System – Natural terrain scattering with density control, noise variation, and masking.
- On Curve System – Perfect for walkways and queues; lets agents follow curves with width and spacing options.
- On Vertex System – Precise, architecturally accurate placements ideal for structured formations.
- Stadium System – Generate entire seating areas with rows, columns, alignment tools, and flexible input methods.
- Walkers System – Path-based crowd flows with lane control, direction settings, and natural variations.
- City System – Smart urban distributions aware of sidewalks, roads, and activity patterns.
Dynamic Movement System
- Fluid System – Real-time simulation with attraction, repulsion, path following, collision avoidance, and full speed control. Integrates directly with any static distribution.
