This is a sub-page of A Hat in Time (Windows, Mac OS X)/Modding Tools Content/Unused Graphics.
Not only does the Modding Tools contain a boatload of unused textures, but there's also quite a lot of unused materials as well. The purpose of some are vague, but many can tell interesting stories about the development of a level. For organization purposes, materials will be divided up into groups. Be aware that some pages may contain a fair amount of animated GIFs.
