ATF
Authoring Tools Framework (ATF) is a set of C#/.NET components for making tools on Windows. ATF has been in continuous development in Sony Computer Entertainment's (SCE) Worldwide Studios central tools group since early 2005. ATF has been used by most SCE first party studios to make many custom tools such as Naughty Dog’s level editor and shader editor for The Last of Us, Guerrilla Games’ sequence editor for Killzone games (including the Killzone: Shadow Fall PS4 launch title), an animation blending tool at Santa Monica Studio, a level editor at Bend Studio, a visual state machine editor for Quantic Dream, sound editing tools, and many others.
