AE图形内渐变投影预设 Inner Shadow v1.1可以快速制作图形内渐变投影，包括修改投影的颜色，位置，程度大小，距离，透明度，叠加方式等Right now After Effects doesn’t offer a native effect for adding an Inner Shadow.

The easiest way is using Layer Styles.

Unfortunately, you need to twirl down several properties until you find what you need.

I built the Inner Shadow preset to match Drop Shadow closely and added a little expression magic to fix some of the controls which I found confusing.
