Grupos de nodos¶
Ejemplo de un grupo de nodos.¶
Grouping nodes can simplify a node tree by hiding complexity and reusing common functionality. A node group is visually identified by its green title bar.
Conceptually, node groups allow you to treat a set of nodes as a single unit. They are similar to functions in programming: reusable, composable, and parametrizable.
For example, suppose you create a «Wood» material and want to use it in multiple colors. You could duplicate the entire node setup for each color, but maintaining those duplicates would be tedious if you later decide to change the wood grain detail. Instead, you can move the nodes that generate the wood pattern into a node group. Each material can then reuse this group and supply a custom color as input. Any updates to the grain detail need to be made only once—inside the node group.
Node groups can be nested; that is, a group can contain other groups.
Nota
Recursive node groups are prohibited to avoid infinite recursion. A group cannot contain itself, directly or indirectly.
Truco
Like other data-blocks, node groups with names that start with . are hidden
from menus and lists and can only be accessed via search.
This is useful for node asset authors who want to hide internal utility groups from end users.
Group Input and Group Output nodes are used to represent data flowing into and out of the group.
The Group Input node provides access to the group’s input sockets from within the node group. These sockets act as parameters that control the behavior of the group from the outside. You can connect them to internal nodes to drive values such as factors, colors, or geometry inputs.
Nota
Input values that do not affect the output will be grayed out.
The Group Output node defines the data that is passed out of the node group. Only sockets connected to this node will be available as outputs on the group itself.
Importante
Avoid using output nodes such as Material Output inside node groups. These should be used on the top level node tree to improve re-usability of node groups.
Use Group Output to pass data out of a node group.
Uso¶
Managing Inputs/Outputs¶
You can add, remove, and reorder input and output sockets in the Group panel in the Sidebar. New sockets can also be created directly by dragging a link to or from the hollow socket on the Group Input or Group Output node to another socket in the node editor.
Reutilización de grupos de nodos¶

- Atajo:
Mayús-A
Los grupos de nodos existentes podrán ser reubicados después de haber sido definidos inicialmente, ya sea en el mismo árbol de nodos o en uno diferente. También será posible importar grupos de nodos desde un archivo .blend diferente, usando .
Truco
When appending node groups from another blend-file, Blender does not distinguish between types such as material or compositing groups. To avoid confusion, it is recommended to adopt a naming convention, like using prefixes (Mat_, Comp_, Geo_, etc.), to indicate the group’s context.
Propiedades¶
Grupo¶

- Panel:
El panel Grupo.¶
This panel contains properties that relate the group node such as its name and look.
- Nombre
El nombre del conector, tal como se muestra en el Título del nodo.
- Descripción
El mensaje mostrado al posar el puntero sobre la barra de Título o en los menús Agregar.
- Etiqueta de color
Etiqueta de color del nodo de grupo, que afectará al color de su encabezado.
- Ancho del nodo
El ancho para los nuevos nodos de grupo creados.
- (Definir ancho predefinido del nodo)
Permitirá definir el ancho basándose en el nodo de grupo superior en el contexto actual
- Show Manage Panel Geometry Nodes
Enables displaying the Administrar panel in Geometry Nodes modifiers when creating a modifier from a node group asset.
Uso Nodos de geometría¶
Este panel sólo será visible dentro del editor de Nodos de geometría.
- Modificador
The node group is intended for use with the Modificador Nodos de geometría.
- Herramienta
El grupo de nodos será usado como una Herramienta basada en nodos.
The data-block menu in the header of the Geometry Node Editor only lists the node groups whose Usage matches the current Node Tree Sub-Type.
Truco
Si de forma accidental se hubieran deshabilitado ambos tipos de uso, el grupo de nodos ya no será accesible a través del menú de bloques de datos. Para volver a hacerlo accesible, podrá ser agregado como un nodo en otro grupo de nodos (), seleccionar ese nodo y pulsar la tecla Tab para ingresar al mismo. Desde allí podrá habilitarse nuevamente uno de los tipos de uso posibles.
Conectores del grupo¶
Referencia
- Panel:
El panel Conectores del grupo.¶
This panel is used to add, remove, reorder, and edit the user interface elements of a node group. It defines how sockets appear on the group node and organizes them for clarity and usability.
Los tipos de elementos disponibles incluyen:
Inputs: Define input sockets for the node group.
Outputs: Define output sockets for the node group.
- Paneles:
Group and organize related sockets together. Useful for structuring complex node setups. Panels always appear at the bottom of the node interface. They can be nested by dragging one panel on top of another in the interface item list.
- Panel Toggle:
Adds a boolean checkbox to a panel’s header, allowing control over its contents. This option is only available when a panel is selected in the interface item list.
Panel toggles have their own options under the Panel Toggle subpanel. Note that toggle sockets are not listed directly in the interface list—panels with toggles instead show a boolean socket icon next to their name. To make the toggle socket visible again, it must be unlinked from the panel.
Nota
A panel toggle does not automatically disable or gray out its sockets. To visually and functionally disable sockets, use a Switch Node or similar logic and disconnect the socket manually.
- Lista de elementos de la interfaz
A UI list view showing all input/output sockets and panels. Each item can be renamed and configured individually. The name appears in the node’s user interface.
Truco
Selecting a socket label on the node itself will also select that socket in the Interface Item List.
Especiales
- Duplicar elemento
Duplicará el conector o panel seleccionado.
- Make Panel Toggle
Converts the selected boolean input into a toggle for its parent panel. Only available when a panel is selected and the active item is a boolean socket.
- Unlink Panel Toggle
Removes the toggle relationship between a boolean socket and a panel, making it a regular stand-alone input again.
Conectores
The properties available for sockets depend on several factors, including whether it is an input or output socket, the data type, and the type of node tree.
- Tipo
The type of Socket generated by this interface item.

The socket can adapt to multiple shapes, making it flexible when used with different connections. Useful for generic node groups intended to handle various data types.
- Individual:
Only allows single values (constants) rather than structured data. Fields or grids cannot be connected.
- Campo:
The socket expects a field, meaning the value can vary depending on the geometry element or context.
- Cuadrícula:
The socket expects a grid data structure, which stores values sampled across a volume or 2D space.

Agrupar¶
Referencia
- Menú:
- Atajo:
Ctrl-G
Creates a new node group that contains all selected nodes.
Group Input and Group Output nodes will be created to represent connections to unselected nodes outside the group. Inputs will be routed to the Group Input and outputs routed to the Group Output.
When grouping a single node, the resulting node group will:
Preserve the interface of the original node, including panels and default values.
Heredará el nombre del nodo original
When grouping multiple nodes, the group is created with inputs and outputs sockets generated from the connections. In this case, a generic name such as «NodeGroup», «NodeGroup.001», etc. is used.
Insertar en grupo¶
Referencia
- Menú:
Moverá los nodos seleccionados al grupo de nodos activo. Para usar esta función, seleccionar un conjunto de nodos, seleccionando por último al grupo de destino, luego al ejecutar esta operación se moverán todos los nodos seleccionados al grupo. Los nodos movidos serán colocados en un grupo propio para preservar su contexto de conexiones, teniendo sus propios nodos de entrada y salida. Los nodos existentes de entrada y salida del grupo de destino serán actualizados con nuevos conectores, si correspondiera, a partir de los nuevos nodos insertados. El grupo de nodos deberá ser editado para que vuelva a contener un solo nodo de Entradas de grupo y uno de Salidas de grupo.

Separar¶
Referencia
- Atajo:
P
The Separate operator removes the selected nodes from a node group and places them in the parent node tree. This is useful when nodes need to be edited outside of a group for clarity or reuse.
- Copiar
Duplicates the selected nodes into the parent node tree, while keeping the originals inside the group. This is useful when you want to reuse nodes outside of the group but still preserve the group definition.
- Mover
Moves the selected nodes to the parent node tree, removing them from the original group. This is useful when simplifying a group or exposing its contents directly.
Join Group Inputs¶
Referencia
- Menú:
- Atajo:
Ctrl-J
Merges multiple selected Group Input nodes into one consolidated Group Input node when possible. Existing links are preserved, and duplicate inputs are unified to reduce clutter and simplify the node tree.
This operation is useful for cleaning up node groups that have become disorganized or contain redundant input nodes.
