I am a programmer who wants to start making a new game, that will be commercial when finished,
getting help with the graphics from freelance pixel artists, and the music from freelance musician, etc..
My question is about the copyright of the art or the music, to whom these rights of the pixel art or music belongs, to me?, to my freelance employee, to both?, can i use
the art of the freelance employee for my commercial use?
I need to put him/her on the credits?, i have to pay him/her something for use the resource in a commercial game?
