Final Topology provides a toolset focused on subdivision surface workflows and retopology. The addon introduces inverse subdivision snapping, continuously evaluating and snapping edit mode vertices so the resulting subdivided mesh closely conforms to a target surface. It includes a live simulation mode for real-time evaluation during modeling and an unsubdivide operator to reconstruct low-resolution control meshes from pre-subdivided geometry. The addon also features a shape freeze function, which maintains the overall subdivided shape while you alter the underlying topology. An advanced tier tailored for CAD and automotive modelers adds constraint optimization, loop sliding angle optimization, normal plane alignment, and customizable weighting algorithms.
