Step 16
Alt + Click the opacity mask to edit it, make a rectangle with a gradient gray to black ( the black makes the object disappear and the white makes the object appear).
16.Alt+点击不透明面板你就可以编辑修改它了，绘制一个矩形，应用灰到黑渐变（黑色使对象隐藏，白色使对象显示）。



Step 17
Do the same thing as before, but use a pointy shape like below as the mask. This time the opacity mask will look like the image below.
17.像之前一样重复操作，但使用尖的形状的不透明面板如下图所示。这次不透明面板如图所示。
