How to make Custom Clipping in NGUI
In Unity, especially in UIPanel in NGUI, there is a feature to do clipping (Hard clipping, soft clipping, and alpha clipping). But all of them are based on rectangular shape. So the bound is rectangle. What I want is to make clipping with bound/shape polygon. Can I achieve that? I thought I have to write my own custom shader, but unfortunately I am a newbie in Unity. So can someone give me a hint the logical step of those steps? I don't know where to start. 
I attached the effect clip I want. The left, is without clipping. And the right is with clipping. The star is a parent which has some clipping shader. And the child inside it will be clipped with the parent's bound.
Thank you
@bangau1 if an answer solves your problem, don't forget to tick it as correct :)
Currently, you can't. But with the new UnityGUI system which will be actually based on NGUI, you can. See this video right here (@19:48), where ArenMook actually shows that feature, as a part of the coming UnityGUI. I don't know if he'll do that in an NGUI 3.x release. But currently with NGUI 3.0.1, it's not there.
