Minimum Fusion Schematic Rig: Two meshes, one Fusion boolean Operation Node, and a Fusion Item.
Meshes must have Fusion-required Tags & User Channels. We recommend using one of our Schematic creation tools that create those mesh properties automatically (New Fusion or Conversion of Tree-Based Fusion Models).


Typical Fusion Schematic Rig: As created by New Fusion or Conversion of Tree-Based Fusion Model.
Fusion Schematics consist of three Node types:
  • Source Meshes - can be any Fusion-Ready* Mesh or Mesh Instance.
  • Fusion Boolean Operation Nodes (Channel Modifiers) - define the Fusion Model's boolean equation.
  • Fusion Item - receives the result of that equation. It's a Modo Item that controls various Fusion settings.
Meshes and Mesh Instances are always linked to Boolean Operation Nodes.
Operation Nodes accept Meshes, Mesh Instances or other Operation Nodes as inputs.
Fusion Item only accepts a single Operation Node as input.

Schematic Fusion Requirements & Limitations



Schematic Fusion Rigs have a few structural requirements/limits:
  • No Non-Fusion Nodes within Fusion Rig - Fusion Operation Nodes only accept Meshes, Mesh Instances and/or other Fusion nodes. All variety of modifiers, deformers etc. can be linked to meshes & mesh instances.
  • Meshes cannot be reused within a single Fusion Model - A Mesh or Mesh Instance may only be linked to a single Fusion Operation node within any given Fusion Item's rig. Use Mesh Instances if you need a single piece of geometry to play several roles in one Fusion Item. Conversely, you a free to link a single Mesh or Mesh Instances to as many different Fusion Item rigs as you like.

Note: You can convert Tree-Based Fusion Models to Schematic, but not the other way around. One practical workflow is to start with Tree-Based to set up your basic boolean structure, then convert — if needed — to a Schematic model for more advanced editing/rigging.

Fusion Schematics & Branches



The inset shows the original Tree-Based Fusion Model used to create this rig.
  1. First Branch's Operation Nodes
  2. Second Branch's Operation Nodes
  3. Branch Intersection Nodes (referred to as the Branch node)
  4. Branch-Merging Union Node (referred to as the Root node)

Schematic Flow of Fusion Branches
  • Those Operation nodes feed into an intersection node [3 - the Branch node]. That Branch node creates all subtraction and intersection booleans among that branch's source meshes.
  • Each of those Branch nodes feed into a Union node [4 - the Root node] that combines all branches.
  • Finally, that Root node feeds into the Fusion Item.
  • All of this is essentially the same as the Fusion 3D Tree branch structure.
