AE吸附空间指定点脚本 Aescripts pointers V1.22 + 教程
不论是在平面还是在三维空间，都可以自动吸附位置属性，并应用到任何图层
Pointers allows you to snap any position property to any layer. It does not matter if it is 3D, 2D or parented. Pointers essentially does all the complicated math for you.
Pointers also gives you controls for keyframable delay and offset. It lets you parent rotation and scale separate from position. You can point lights or cameras to layers with a few clicks. 2D Effects can follow 3D layers and much more.
