How do I mask live2D characters in Unity?

CreativeVirus

I have read "Masking.scene" and "Description.txt" in Live2D's Unity Runtime example folder.
However, I did not understand the information on how to Masking (Clipping) my Live2D character in Unity.

My goal is to mask my Live2D character to a square Sprite Image.
Unity version is using 5.6.3f1.

I want this problem fixed.

The sample project called Masking is for users to utilize clipping mask set on a Cubism model in Editor.
If other masking expressions are necessary users need to make a script.
