Break to Paths
Breaks clusters edge chains into individual paths
The Break Clusters to Paths node converts edge chains into individual paths, offering a quick way to extract paths or splines from a refined topology without requiring complex pathfinding, but is less suited for dense clusters with highly connected vertices.

The Break Cluster to Path turns all Edges
chains to individual paths. It’s useful to quickly get a bunch of paths or splines out of a refined topology without the need for pathfinding.
It is not recommended to use this node on very dense clusters (where a lot of
Vtx
have more than two connections), as it quickly ends up creating a single point data per individual edge.
Properties
Property | Description |
---|---|
Operate On | Lets you choose how to break cluster down. - Paths : Operate on edge chains which form paths with no crossings. e.g, nodes with only two neighbors.- Edges : Operate on each edge individually (very expensive) |
Direction
Property | Description |
---|---|
Direction Method | Defines which endpoints “order” will be used to define the direction reference for the ouputs. |
Direction Choice | Further refines the direction method, based on the above selection. - Smallest to Greatest will order direction reference metrics in ascending order.- Greatest to Smallest will order direction reference metrics in descending order.Really it’s how the endpoint reference value is sorted, but I couldn’t call that Direction’ direction. |
Dir Source Attribute | The attribute that will be used by the selected method. |
If the selected method is
Endpoints Attribute
, the attribute is will be read fromVtx
as adouble
. If the selected method isEdge Dot Attribute
, the attribute will be read fromEdges
as anFVector
direction.
Method
The Direction method
, combined with the Direction Choice
determine which endpoint should be considered the Start
& End
of the edge. The “direction” of the edge used for computing outputs & properties is the safe normal going from the start to the end of the edge.
Mode | Description |
---|---|
Endpoints order | Will use the endpoints’ as ordered during cluster construction. |
Endpoints indices | Will use the endpoints’ point index. |
Endpoints Attribute | Will use an attribute (converted to a Double ) from the endpoints’This method, combined with Direction Choice offers full control over direction.
|
Edge Dot Attribute | Will use an attribute (converted to an FVector ) from the edges’ and do a Dot Product with the edge’ direction.This method, combined with Direction Choice offers full control over direction.
|
Using
Edge Dot Attribute
only uses the first available edge in the chain to infer direction.
Pruning
Min Point Count | This lets you filter out output paths that have less that the specified number of points. |
Max Point Count | If enabled, this lets you filter out output paths that have more that the specified number of points. |
Using Break Conditions
The break condition filters can be used to get tighter control over when to split a clean edge chain into more sub-paths than the default behavior. If the point pass the specified filters, it will stop whatever path was being created. If the point

The Mean Value Filter compares per-point values of an attribute against the mean statistical value of that same attribute.
