RetopoFlow is a full retopology mode for Blender that helps make quick work of creating custom, clean, mid or low poly meshes on top of high resolution sculpts.

The separate mode helps us not only get more information about the models than Blender can give by default (so our tools can work more effectively than anything else available today), but also to display the geometry in a more helpful manner. RetopoFlow mode’s custom mesh rendering is currently the only way in Blender to see low poly geometry cleanly overlaid on a high poly mesh without overlap, distortion, or depth sorting issues.
