Utility nodes are mainly for mathematical operations with fields, values and elements.

For Each Element

The For Each Element Node enables iterative operations on individual elements of a geometry. This node is ideal for tasks requiring unique processing for each element, such as creating distinct objects or attributes for every element: a face, vertex, or curve or other domain.

Note: The For Each Element Node is best for creating detailed or complex geometry for every element of an input. For instance, you can use it to generate a unique tree for each curve or a distinct building on every face of a mesh.

However, it's less efficient for handling tiny elements, like individual strands of hair. Processing small parts separately can slow things down because Blender isn’t able to optimize the operation effectively. For projects with many elements, it's better to design your node setup to avoid working on very small pieces one at a time. In this case, it is best to run operations directly on field domains.

For Each Element Input

Inputs

Entry	What it does
Geometry	The input geometry whose elements will be processed individually. This can include meshes, curves, or other geometry types.
Selection	Specifies which subset of elements to process. This allows filtering based on boolean attributes or conditions per field – typically used as a true/false mask.

Properties

Element

Defines which element of which domain will be used.

The input geometry is divided into individual geometries, each corresponding to a single element. During each iteration, the node processes one of these single-element geometries.

Note: However, this functionality does not apply to the Face Corner domain, as face corners are inherently tied to their parent face and cannot exist independently.

Output

Entry	What it does
Index	Provides the Index integer of the current elements of the selected domain to be processed.
Element	Returns a Geometry output with the list of elements for iteration.

For Each Element Output

Inputs

Main Geometry

The Main Geometry outputs create attributes on the "main" output geometry (the first output). Each value calculated within the zone becomes part of the attribute at the corresponding index of this output.

Note: Default is blank.

Generated

Result of joining generated geometries from each iteration.

The Generated inputs contain the individual geometry elements processed inside the zone. This includes any fields and attributes from different domains associated with these elements.

Note: Default is the result of joining generated geometries for each iteration.* *You can connect any new attribute or filed and output new generated elements and custom fields from the zone.

Properties

Entry	What it does
Main Geometry	The main geometry sockets.
Generated Geometry	The generated geometry sockets from the zone.

Socket Type

What input input and output socket type to evaluate from each iteration in the zone.

Inspection Index

Iteration index that is used by inspection features like the viewer node or socket inspection

Output

Entry	What it does
Geometry	The original input geometry with potentially new attributes that are output by the zone.
Element	Result of joining generated geometries or attributes from each iteration.

Index Switch

The Index Switch node is meant as a simpler version of the Menu Switch node. It doesn't allow naming items or displaying them in a dropdown, but still allows choosing between an arbitrary number of items, unlike the regular Switch node where you can just switch between two states.

Inputs

Index

Wich input to choose.

0 , 1 ...

The available input index types that you want to switch between. You can define more input sockets in the sidebar.

Properties

Data Type

What input type to evaluate.

Outputs

Output

The output index.

The Menu Switch node selects and computes one input based on a user-defined menu. Only the selected input is computed.

Menu entries can be added, removed, renamed, and reordered. Renaming keeps existing input links.

The menu can be used in node groups and the nodes modifier UI. Connecting the menu to a Group Input node exposes it as a group input. A menu needs to be connected to a Menu Switch node to work. An unconnected menu is empty.

Connecting multiple Menu Switch nodes to the same output creates a conflict. To avoid this, a menu switch can be grouped. Multiple groups of the same type can connect to the same menu.

Note: You cannot plug in the same value socket into the Menu selector. If you’d like to use the same value for various Menu Switches, group the Menu Switch into a Node Group and use the top-level switch override.


Top Level Grouped Menu Switches with same inputs:	Conflict caused by Same Level menu Switch inputs:

Inputs

A / B

Becomes the output if the value is chosen.

Determines which of the input options will be selected and passed through as the default.

Note: You can add more menu switch options to the empty socket.

Output

Value

Repeat

When adding a repeat zone, two nodes are added with a “zone” set between them. The inputs connected to the Repeat Input node reads and gets data at the beginning of the loop before starting the looping - then the data is processed within the zone, here you can set any changes to the data to then repeat the execution again at the beginning of the chain for the next iteration of the loop. This chain of operations is repeated the specified number of times in the Repeat Input node.

In the example in the image above, we duplicate the cube, transform it with a rotation, then join it together again. We do this 8 times in a loop, creating a circular array.

Note: It is not possible to set data outside the Repeat Zone, you can only get data from outside the Repeat Zone. Any data connected from the outside of the zone are constant throughout every iteration based on their value at the current frame. The result of the looping can only be accessed via the Repeat Output node.

Closure

Vector nodes are for calculating vector operations.

Closures allow you to pass custom logic into node groups—like injecting a mini-function or behavior block. They’re ideal for creating reusable, pluggable systems where the user can define part of the logic externally.

Closure Zone

The closure function to be executed.

Purpose

Defines logic that will be injected into a node group or node tree. Think of it as a sandbox where the user builds a mini-node tree that gets executed when the closure is evaluated during the execution of another node tree.

A Closure encapsulates the logic defined in the Closure Zone. This output is typically connected to an Evaluate Closure node inside a node group or injected into another node tree.

Use Cases:

Custom deformation logic injected into a reusable node group.
Procedural scattering patterns defined externally.
Field-based attribute manipulation with user-defined formulas.
Behavior overrides for geometry processing pipelines.

Behavior

The Closure Node creates a Closure Zone—a subgraph where the logic is built using the declared inputs. This zone behaves like a function.

Closure Inputs appear as sockets at the top of the zone. Data from outside the zone can also be referenced.
Outputs are defined using Closure output nodes.

The logic inside is encapsulated and only runs when evaluated externally.

How It Works (Conceptually)

Authoring: You define a Closure Zone with custom logic (e.g., a tree scattering pattern).
Packaging: The Closure node wraps that logic into a closure line.
Injection: Inside a node group or elsewhere in a node tree, the Evaluate Closure node pulls in that logic and runs it with the provided inputs.
Modularity: You can swap closures to change behavior without modifying the node tree or nodegroup itself.

When the node group containing an Evaluate Closure node runs, it pulls in the logic from the Closure Zone and executes it in place. The zone is not executed immediately—it’s stored as a callable block.

Requirements

Input and output names in the Closure Zone must match those expected by the Evaluate Closure node.

Can include any Geometry Nodes logic, including fields, math, distribution patterns, etc.

Properties

These panel defines the parameters that the closure will pass when evaluated. Each item becomes a socket in the Closure Zone.

You can access these properties in the sidebar to the right in the Node tab.

Output Items	Whatever parameters the Closure logic returns—could be geometry, fields, instances, values, etc

It passes in the provided parameters and returns the result of the closure’s internal node tree. Execution is deferred—the logic only runs when this node is evaluated in the context of the node group.
