Field 2D Root

Updated: 7 Aug 2025

Method #

This node is the root node and container for any 2D Field system. Field Emitters, Affectors, Colliders, and Rendering nodes should be parented to this node directly or indirectly in order to be operational. 2D Fields are optimised for 2D and runs a bit faster than you might expect. This does mean some emitters and affectors which run in 2D might not work in 3D, and vice versa.

The Field 2D Root node contains all of the parameters to control all of the parameters of your 2D Field system, and determine it’s resolution.

As the Root node, it contains a number of controls that are globally effective across the system, and can have wide ranging effects on the simulation. With Fields in particular, much of the motion and shape of the simulation is derived from the simulation properties, therefore familiarity with the settings below is a must for adept use of a field system.

As a root of a Field system, all subsequent field nodes need to connect to this node.

Post-FX nodes can be applied directly to a Field 2D Root in order to alter the visual output.

The Field 2D root can be used in 3D space by parenting it directly to the root node of your project. Alternatively, parenting the Field 2D Root to a 2D Root node lets you use this Field system in a purely 2D workflow.
