Normal maps allow you to create amazing realistic lighting for games. This tool is designed to highlight 2D sprites in 2D games, but can also be used for 2D textures in 3D games.
Specular Maps allows you to create a realistic shine on your sprites.
Parallax Maps will “deform” the texture depending on the point of view, so you can create, for example, depth effects on the background, such as brick walls.
Ambient Occlusion Maps let you determine which parts of the environment the light should be weaker to.
