Collision

Updated: 2 Feb 2026

Introduction #

These nodes allow for a Field systems to collide with surfaces, limiting areas the field can travel and creating secondary shapes from the new collision surface.

Collision nodes should be parented to a field root node, either a Field 2D Root or a 3D Field Root.

Use the collision velocity parameter on the collision node to determine the resulting velocity from any collisions between the surface and the field.

Mesh Collision Affector

Allows fields to collide with 3D Meshes.

Primitive Collision Affector

Allows fields to collide with primitive shapes.

Procedural Collision Affector

This node allows fields to collide with procedurals.
