I am making a game made with Fps kit and I used most of the environment assets in Bootcamp, Angrybots, and stealth made by unity techonologies. is it ok to sell my product on internet or is there copyright issues???:?:?:?
Yes, it’s ok. The Unity sample content is allowed for commercial projects.
I usually confirm that it’s free to use, but then point out that the Unity content is very recognisable, so once you publish your game you can expect reviews which say it just “steal” Unity content. It’s a bit confusing how a single game can use assets from 3 very different demos and look cohesive. I’d recommend if you get to a point where you have something you want the world to see/buy you invest in some artist time, and get some artwork created specifically for your game, and just use the Unity ones as placeholders for now.
