IDMapper simplifies creation and editing of vertex color layers that can be used as ID-maps in texturing software like Substance Painter or Quixel. It aims to reduce the time it takes to create an ID-map significantly, especially for complex hard surface models.
It uses powerful heuristics to create an ID-map from scratch and lets you interactively adjust the results. It offers options to use existing information, like uv-seams, but can also intelligently assign the same color to similar mesh parts.
You can even paint faces by hand in a way that unlike regular vertex painting allows you to apply uniform colors to to entire faces (instead of interpolating the vertex colors over the face), which is convenient when useing the vertex colors as id-maps.
