CC-BY-SA 3.0 with Unity3D

Hi, 

I am developing a game with unity3d and closed source plugin.

I want to use LPC asset licenced under cc-by-sa 3.0 in my game.

but the problem is that cc-by-sa 3.0 require me source code to be released.

I can share my own source code except unity3d source code and closed source code of plugin.

So I finded and read posts related with this issue.
