This setup launches a burning rock like a catapult.

This setup divides particles randomly into 3 groups. These groups are then affected by different forces to divide them into 3 piles.
This setup uses a collider to unstick particles from another spinning collider to give the impression of a piece of wood beeing cut on a lathe.
A set of node to randomly delete particles in order to reduce the particle count.
This setup splits particles by particle-id and let only one stream collide with geometry.
A set of attrib-set nodes to create a procedural sphere from a grid. The nodes can be copy-pasted into other scenes.
A set of attrib-set nodes to create a procedural torus from a grid. The nodes can be copy-pasted into other scenes.
