CC-BY-SA 3.0 with Unity3D
Wednesday, October 2, 2013 - 00:51
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.

but I have been stil confused whether It's ok to use Lpc assets or not.
can I use LPC asset in my game?
please leave a your opinion.
I'm sorry for lack of my English skill.
You can use CC-BY-SA assets with Unity just fine.

In general, source code and the compiled executable can each be licensed separately. We know this because we buy regular games that don't come with the source.
CC-BY-SA 3.0 does not require you to release any source code. It has nothing to do with "source code". You may be thinking of software licenses such as the GPL which purposefully interlink the source and compiled code licensing.
Someone might argue that the final, total game is a derivative work of the individual art and compiled code. But your released game would be the derivative work then, not any of the source code. And that's the strictest accepted interpretation of CC-BY-SA for games.
Just like Clint said, CC-BY-SA does not require you to share source code.
Though it's not directly said, game is "Collection", not "Adaptation". My reasoning can be found from other thread:

To me it seems strange that OpenGameArt FAQ states that you should release source of entire project under compatible license if you use CC-BY-SA . Well, IANAL.
Thank you for reply!!
