Giới Thiệu (Introduction)

The different node editors are used to work with node-based workflows. Each node editor type has its own specific purpose. Therefore, this section only explains how to work with nodes in general. In the list below it shows a list of different types of node trees and where each is documented.

Tiêu Đề (Header)

The Header contains various menus, buttons and options, partially based on the current node tree type.

../../../_images/interface_controls_nodes_introduction_header.png — Common node editor header options.

Góc Nhìn (View): This menu changes your view of the editor.
Chọn (Select): This menu allows you to select a node or groups of nodes.
Cộng Thêm (Add): This menu allows you to add nodes.
Nút (Node): This menu allows you to do things with selected nodes.
Sử Dụng Nút (Use Nodes): Tells the render engine to use the node tree when computing the material color or rendering the final image, or not. If not, the tree is ignored. For materials, this is mostly a legacy option, because in the past materials could not be created with node trees.
Sử dụng Ghim Lại (Use Pinned): When enabled, the editor will retain the material or texture, even when the user selects a different object. A node tree can then be edited independent of the object selection in the 3D Viewport.
Cây Nút Phụ Huynh (Parent Node Tree): This button allows you go to parent node tree e.g. leaving a group.
Bám Dính (Snapping): Change options for snapping node positions to achieve a cleaner node tree layout.

Lớp Vẽ Lồng (Overlays)

Overlays are information that is displayed on top of the nodes and node trees. There is a toggle to show or hide all overlays for the node editor next to the overlay popover.

Hiện Màu Dây (Wire Colors): Tô màu liên kết của nút dựa trên các ổ cắm được kết nối của chúng.

Context Path: Display breadcrumbs in the upper left for the current node tree's datablock location.

Chú Thích (Annotations): Displays Annotations in the preview region.

Điều Hướng (Navigating)

Navigating the node editors is done with the use of both mouse movement and keyboard shortcuts.

Lia NCG (MMB): Lăn/Xoay góc nhìn trái/phải.
Thu-Phóng Ctrl-NCG (MMB), Bánh Xe (Wheel) (Zoom Ctrl-MMB, Wheel): Move the camera forwards and backwards.
Đóng Khung quanh cái đã Được Chọn Dấu Chấm (.) Bàn Số (NumpadPeriod): Adjusts the zooms to fit only the selected nodes in the view.
Toàn bộ các khung hình Home: Adjusts the zoom to fit all nodes in the view.

Cho thêm các nút (Adding Nodes)

Tham Chiếu (Reference)

Trình Đơn (Menu): Add (Cộng Thêm)
Tổ Hợp Phím Tắt (Shortcut): Shift-A

Nodes are added via the Add menu which can be accessed from the Editor's Header or using shortcut.

Nodes can also be added by dragging a connection from an existing node's input or output socket and dropping the connection above an empty space instead connecting to another socket. This action will open a search menu with a list of compatible nodes and their sockets that can be added and connected to the existing node. Confirming the menu selection will add the node which can be moved and placed in the node tree space.
