AE图层位置匹配跟随脚本 Aescripts Match Position V1.1 For After Effects CC 2014 +

1. 一键在选定图层上创建空值。根据选择将空值设置为 2D 或 3D。按住 ALT 键单击可自动成为所选内容的父级。按住 SHIFT+ALT 键单击以使其成为所选内容的父项。

2. 匹配层之间的位置和方向，无论父结构如何。选择两个图层并单击。第一层将转换为目标层的 3D 空间并捕捉到其位置和方向。在操纵角色和构建 3D 环境时非常有用。按住 ALT 键单击可自动设置父级。

3. 将 2D 屏幕空间值链接到 3D 位置坐标。对于以下方面来说非常宝贵：

• 信息图表标签和图标需要保持与 3D 图层和 3D 相机移动相关的尺寸一致
• 需要跟踪 3D 图层坐标的 2D 效果坐标（光束、镜头光晕、无线电波、Knoll Light Factory 等…）
• 任何需要 2D 图层才能查看 3D 坐标的设置
• 奖励：After Effects 不允许单节点相机链接到焦点对象。匹配位置可让您进行设置。选择单节点相机和任意 3D 图层，单击“链接位置”按钮，相机的焦距将自动跟随 3D 图层。

4. 分布层。至少选择三层，中间的选择将分布在第一层和最后一层之间。要进行更精细的控制，请仅选择三个图层，然后按住 ALT 键并单击以输入中间选择的距离百分比（例如，将中间图层设置为第一个图层和最后一个图层之间距离的 25%）。一种超级简单的方法来分布视差层，并具有对距离的控制感，否则会感觉很随意。也适用于相机、灯光以及 2D 图层选择。

1. Create Nulls at selected layers with one click. Nulls are set to 2D or 3D based on the selection. ALT-click to automatically parent to the selection. SHIFT+ALT-click to make it a parent of the selection.

2. Match position and orientation between layers, regardless of parent structure. Select two layers and click. The first layer will convert to the target layer’s 3D space and snap to its position and orientation. Super helpful when rigging characters and building 3D environments. ALT-click to automatically parent.

3. Link 2D screenspace values to 3D position coordinates. Invaluable for:

• Infographic labels and icons that need to maintain consistent sizes in relation to 3D layers and 3D Camera movements
• 2D effects coordinates that need to track 3D layer coordinates (Beam, Lens Flare, Radio Waves, Knoll Light Factory, etc…)
• Any setup that requires 2D layers to see 3D coordinates
• BONUS: After Effects does not allow a One-Node Camera to link to a focus object. Match Position lets you set this up. Select a One-Node Camera and any 3D layer, click the “Link Position” button, and your camera’s Focus Distance will automatically follow the 3D layer.

4. Distribute layers. Select at least three layers, and the middle selections will be distributed between the first and last. For more granular control, select only three layers and ALT+click to enter a distance percentage for the middle selection (e.g. Set middle layer at 25% of the distance between first and last). A super easy way to distribute parallaxing layers with a sense of control over distances that can otherwise feel arbitrary. Also works with Cameras, Lights and between 2D layer selections.
