Nhóm Nút (Node Groups)¶
Ví dụ về nhóm nút.¶
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.
Ghi chú
Recursive node groups are prohibited to avoid infinite recursion. A group cannot contain itself, directly or indirectly.
Mẹo
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.
Ghi chú
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.
Quan trọng
Avoid using nodes 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.
Cách Dùng [Usage]¶
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.
Tái Sử Dụng các Nhóm Nút (Reusing Node Groups)¶

Các nhóm nút hiện có có thể được hoàn lại sau khi chúng được định nghĩa lần đầu tiên, cho dù là trong cùng một cấu trúc cây nút hoặc ở một cây khác. Chúng ta cũng có thể nhập khẩu các nhóm nút từ một tập tin blend khác bằng cách sử dụng .
Mẹo
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.
Tính Chất (Properties)¶
Nhóm (Group)¶
Tham Chiếu [Reference]
- Panel (Bảng):
The "Nhóm" bảng.¶
This panel contains properties that relate the group node such as it's name and look.
- Tên [Name]
The tên của nút as displayed trong giao diện-nút-phần-đầu đề (interface-nodes-parts-title).
- Miêu Tả [Description]
The message displayed when hovering over the Đầu Đề (Title) or in add menus.
- Nhãn Màu (Color Tag)
Color tag of the node group which influences the header color.
- Chiều Rộng Nút [Node Width]
The chiều rộng cho/đối với newly created các nút nhóm.
- (Đặt Mặc Định Chiều Rộng Nút [Set Default Node Width])
Set the width based on the parent group node in the current context
- Show Manage Panel Geometry Nodes
Enables displaying the Quản Lý [Manage] panel in Geometry Nodes modifiers when creating a modifier from a node group asset.
Cách Dùng [Usage] Các Nút Hình Học (Geometry Nodes)¶
This bảng được duy hữu hình trong Trình Biên Soạn Nút Hình Học (Geometry Node Editor).
- Bộ Điều Chỉnh
The node group is intended for use with the Bộ Điều Chỉnh các Nút Hình Học (Geometry Nodes Modifier).
- Công Cụ (Tool)
The node group is intended to be used as a tool.
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.
Mẹo
If you accidentally disable both Usages, the node group will not be accessible through the data-block menu anymore. To make it accessible again, you can add it as a node to a different node group (), select that node, and press Tab to enter it. From there, you can enable one of the Usages again.
Nhóm Ổ Cắm [Group Sockets]¶
Tham Chiếu [Reference]
- Panel (Bảng):
The "Nhóm Ổ Cắm" bảng.¶
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.
Available item types include:
Inputs: Define input sockets for the node group.
Outputs: Define output sockets for the node group.
- Panels:
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.
Ghi chú
A panel toggle does not automatically disable or grey out its sockets. To visually and functionally disable sockets, use a Switch Node or similar logic and disconnect the socket manually.
- Interface Item List
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.
Mẹo
Selecting a socket label on the node itself will also select that socket in the Interface Item List.
Đặc Biệt (Specials)
- Duplicate Item
Duplicates the selected socket or panel.
- 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.
Ổ Cắm (Sockets)
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.

Tạo Nhóm (Make Group)¶
Tham Chiếu [Reference]
- Trình Đơn [Menu]:
- Tổ Hợp Phím Tắt [Shortcut]:
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.
Inherit the name of the original node
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.

Tách Rời (Separate)¶
Tham Chiếu [Reference]
- Tổ Hợp Phím Tắt [Shortcut]:
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.
- Sao Chép (Copy)
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.
- Di Chuyển (Move)
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¶
