he has the 3d studio to make the 3d characters,and he's going to get maya to build the exterior and interior of the game,
the problem is he does not know the process of putting things together after having made every different part(grafics,sound,script...)
he does not want to use an adventure maker because he wants the game to be original in a way,does anyone knows the process?
should my friend have extensive knowledge of programming ?
