当你把一个蒙版遮罩从一图层复制到另一个图层经常改变其位置。CopyMask2Layer可以完美解决这个问题，即使这个图层是运动的或者遮罩有关键帧，CopyMask2Layer适用于任何2D图层。
CopyMask2Layer 2
When you copy a mask from one layer to another it often changes its position. With CopyMask2Layer you can copy masks while keeping them perfectly in place – even if the layers are moving and if the mask path is keyframed.
CopyMask2Layer works with masks on any 2D layers.
New in Version 2
Version 2 of CopyMask2Layer natively supports rotobezier masks.
