How to make transparent and receive shadow shader?

[모노소프트웨어]

My game`s tile map(unity built in) use png sprite with tranparent part.

So in Unity's default sprite shader, the place where it should look transparent looks transparent. But the default sprite shader did not receive any shadow.

In the other hand, if you use Unity's standard shader, the shadows are well received, but the place to be transparent is not transparent.

So I used Legacy/Tranparent/Cutout/Bumped Diffused shader.. But there was also a problem. The legacy shader did not receive point/spot light`s, only recieve from direction light.

Please help me. I bought shadero asset, but I can`t solve problem.
