Particle Flocker is a particle-based flocking system integrated into Autodesk Maya, designed for both visual quality and ease of use.

Harnessing the power of Maya's dynamics systems, Particle Flocker utilises a force field system, allowing animators to apply flocking behaviour to any particle-based system in Maya. Particle Flocker is one of the most versatile and yet easy-to-use flocking systems currently available for Maya.
