反转选区Outside Node

先学：Prerequisites: 窗口

学习目标LEARNING OBJECTIVES

学完你能用 Outside 节点一键反转选区，调整窗口之外的区域，并让"窗内窗外"两套调整并列共存。

概念说明CONCEPTS

Outside 节点（Outside Node）是把上一节点选区自动取反的新节点——窗口里的区域刚调完，一个快捷键就开始调"剩下的所有地方"，不用重画互补形状。

  • 一键生成：选中带选区的节点，右键 Add Node > Add Outside（快捷键 Option-O/Alt-O）。
  • 蓝色键连线：新节点多出蓝色三角的 Key 输入输出——它接收上一节点的遮罩并自动反转（见 键信号）。
  • 遮罩只画一次：窗口（或限定器）的选区正反两用；改窗口形状，两边同步更新。
  • 典型分工：节点 02 调窗内（如主体），Outside 节点 03 调窗外（如环境），各自独立开关。

操作步骤STEPS

  1. 在 Node Editor 选中带窗口的节点（橙色描边）
  2. 右键选 Add Node > Add Outside（或按 Option-O/Alt-O）生成 Outside 节点
  3. 右键新节点选 Node Label 命名，如 BACKGROUND
  4. 点检视器左上角 Highlight 确认：窗内盖灰、窗外正常
  5. 在 Outside 节点上调整——效果只落在窗口之外
  6. 再按 Highlight 关闭，按 Command-D/Ctrl-D 对比调整前后

练习PRACTICE

  1. 给一个带窗口的节点加 Outside 节点：窗内提亮主体、窗外压暗环境，命名后逐一开关对比。
  2. 回到窗口节点改一下形状或位置，观察 Outside 节点的选区是否同步变化。

常见问题FAQ

Outside 节点和重画一个大窗口有什么区别？

重画等于维护两张形状，改一处另一处就错位；Outside 共用同一张遮罩并自动取反，改窗口两边同步。

我在 Outside 节点上调整，窗内怎么也变了？

多半是上一节点还没有选区。没有遮罩可反转时，Outside 节点作用于全画面——先确认源节点画好了窗口。

想再调回窗内那一侧怎么办？

对 Outside 节点再做一次 Add Outside，选区会再反转回来；也可以新开串行节点重新画选区。

同一个节点里不能直接反转窗口吗？

窗口面板里有反转选项，但"内""外"只能留一套调整。Outside 节点让两套调整并列、各自开关——这正是节点工作流的优势。

Learning Objectives学习目标

After this card you can invert a selection with an Outside node, adjust everything beyond the window, and keep the inside and outside grades side by side.

Concepts概念说明

An Outside Node is a new node that automatically inverts the previous node's selection — finish grading inside the window, then one shortcut starts you on "everywhere else", with no mirrored shape to redraw.

  • One shortcut: select the node holding the selection, right-click Add Node > Add Outside (Option-O/Alt-O).
  • The blue key link: the new node gains blue-triangle Key input/output — it receives the previous node's mask and inverts it automatically (see Key Signal).
  • Draw the mask once: the window (or qualifier) selection works both ways; reshape the window and both sides update together.
  • A classic pairing: node 02 grades inside (e.g. the subject), Outside node 03 grades outside (e.g. the environment) — each toggles independently.

Steps操作步骤

  1. In the Node Editor, select the node holding the window (orange outline)
  2. Right-click and choose Add Node > Add Outside (or press Option-O/Alt-O)Adding an Outside node
  3. Right-click the new node, choose Node Label, and name it, e.g. BACKGROUND
  4. Click Highlight in the viewer's upper left to confirm: gray inside, normal outside
  5. Grade on the Outside node — the effect lands only beyond the window
  6. Turn Highlight off, then press Command-D/Ctrl-D to compare before and after

Practice练习

  1. Add an Outside node to a windowed node: brighten the subject inside, darken the environment outside; label both and toggle them one by one.
  2. Go back to the window node, change its shape or position, and watch the Outside node's selection follow.

FAQ常见问题

How is an Outside node different from redrawing a big window?

Redrawing means maintaining two shapes — move one and the other goes stale. Outside shares one mask and inverts it, so both sides stay in sync.

My Outside node adjustment changed the inside too?

The previous node probably has no selection yet. With no mask to invert, an Outside node affects the whole frame — make sure the source node's window is drawn.

How do I grade the inside again?

Add Outside once more on the Outside node and the selection flips back — or add a plain serial node and draw a fresh selection.

Can't I just invert the window on the same node?

The Window palette has an invert option, but then you keep only one of the two grades. Outside nodes keep both side by side, each switchable — the whole point of a node workflow.
