【教程简介】
使用过AE的朋友都只在AE时间线是上面的图层会挡住下面的图层，
如果想让下面的图层出现在上面图层上，需要手动Ctrl+D复制然后把下面的剪切移动到上面图层，
但是一个合成里面这样的操作太多就会导致图层混乱，不便查找和整理图层，
那么这个 Layer Slayer 脚本可以一键切换图层之间的前后遮挡关系，非常方便
If you’ve ever worked in a moderately complex composition, at some point you’ve probably found yourself caught in some unholy vortex of pre-comping, layer duplication and keyframe copying and pasting – just because you need the same content to appear in different layers. Layer Slayer is the workflow tool that will free you of all this nonsense. Use it to summon a perfectly synced copy (called a “Slayer”) of any layer you like (the “Master”). The Slayer goes wherever and whenever you need it in the timeline layer stack, and the Master sends its content there with a single click anytime you choose. You keep working on the Master Layer and let Layer Slayer keep the visuals in perfect sync. There’s no limit to how many Slayers you can create for a single Master, it’s one click – no matter how complex you’ve made it.
