Geometry Node Particle System

This tool provides a custom particle simulation toolkit built within Blender's Geometry Nodes framework. It includes primary node groups for managing particle instances, generating procedural trails, and spawning child particles. Additional control nodes handle velocity editing, allowing particles to react to surfaces, curves, and spherical fields.

The simulation evaluates particles using named attributes such as age, lifetime, mass, rotational velocity, and overall size, all of which can be passed to the Shader Editor for custom material effects. The system also includes tools to align instances to the active camera, ignore object transforms, and calculate experimental mesh collisions using either particle size or raycasting techniques.
