NodeWorks
This is a node based editor that includes FumeFX particles, cloth, soft body, rigid body dynamics, fluid components as well as integration with FumeFX fluid simulation.
Particles are organized in groups and clusters. While groups and group properties are user defined and user can assign each particle to a pre-defined group, clusters are automated and based on procedural approach.
In order to create a FumeFX NodeWorks in your scene, simply go to the Create Command Panel and from the Geometry dropdown menu select FumeFX option and then create NodeWorks.
