Layer Group 层组
A layer group lets you group multiple layers and have them show up on a single layer. It’s useful for organizing your projects as well making it easier to animate multiple layers at the same time. It’s similar to the Layer Groups in Sketch and Photoshop, except that it has a size that it will crop its contents to.
一个层组可以让你将很多个层组合在一起并显示在一个层里。它对于组织你的项目非常有用，很容易让很多个层同时动画。与photoshop和skech里的层组很像，除了它有尺寸并且它会剪切它的内容这一点。
Input port
Render 渲染
Turning this off will disable all the patches inside the Layer Group from running. Using this port to turn off rendering when your layer group isn’t visible may help you improve performance. However, note that Origami Live does not support turning this port off at this time (although it will support disabling Layers to achieve similar performance gains).
关闭这个选项会让层组里的内容不可见。使用它来使你的层组不可见会提升性能。然而，Origami Live目前还不支持(尽管它会支持层不可见也会同样的提升性能)。
