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.

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.

Legend

- First Branch's Operation Nodes
- Second Branch's Operation Nodes
- Branch Intersection Nodes (referred to as the Branch node)
- 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.
