A geometry node modifier that provides a particle simulation system. Applied directly to an emitter object, it generates particles dynamically during animation playback. The system includes built-in parameters for spawn rates, lifetime, initial velocity, and environmental forces like gravity, wind, and drag.

The modifier supports advanced behaviors including mesh and self-collisions, custom object instancing, and continuous mesh ribbon trails. It integrates with Blender's material system by exposing numerous simulation attributes, such as age, hit count, velocity, and trail UVs, which can be accessed via the Attribute node in the Shader Editor.
