Retopo MT is an edit mode add-on designed to assist with retopology workflows. It integrates with the BSurface add-on, allowing users to generate new polygons by drawing guide lines from selected vertices. The tool provides specialized input methods for creating topology, including a contour style for drawing lines and an auto-merge function for combining vertices.

Users enter a dedicated retopology mode where standard inputs are temporarily mapped to specific retopology functions. Features include adjustable cut counts, mirror toggling, quick face deletion, and a brush-based selection tool for isolating specific points during the retopology process.
