什么是子图
这是一个将多个节点合并为一个节点的功能。 不仅可以整理外观，还可以将其作为可复用的模块（Blueprint: 蓝图）保存，并像新节点一样进行处理。
虽然可以将所有节点整合成一个，但 ComfyUI 的特征在于可以将图像生成管道划分为小的模块。
我个人认为，与其说它只是为了整顿外观，不如说是为了创建“可复用模块”而存在的功能。
创建子图
-
- 选中多个想要合并的节点
-
- 点击
Node Selection Toolbox的🕸️(Convert Selection to Subgraph)
- 点击
编辑子图
双击子图，或点击右上角的图标进入编辑模式。
基本操作与通常相同，但与外部交互的参数需要连接到子图的输入输出插槽（左侧/右侧）。
公开参数设置
可以将子图内的参数，作为子图节点的 Widget 公开表露出来。 这样无需每次都进入编辑模式即可更改数值。
-
- 选中子图
-
- 点击
Node Selection Toolbox的Edit Subgraph Widgets
- 点击
-
- 勾选想要公开的参数
子图的保存与复用
保存创建的子图后，可以将其作为独特的节点进行复用。
-
- 选中子图
-
- 点击
Node Selection Toolbox的📖(Publish Subgraph)
- 点击
-
- 输入名称并
Confirm
- 输入名称并
保存后，可以像普通节点一样通过搜索（双击）进行调用。
也可以从侧边栏的节点库中确认，并在此处进行 Blueprint 的删除或编辑。
