OkTopo Remesher is an add-on that automates the retopology process for 3D head models. It uses a marker-based workflow to wrap a clean, quad-based topology around high-poly sculpts or 3D scans. Users place controllers to guide the edge flow, ensuring the generated mesh maintains proper loops for facial animation, blendshapes, and rigging.

The generated topology includes automatic UV unwrapping, reducing the setup time required before texturing. The add-on features adjustable polycount settings to output geometry suitable for various asset pipelines, from real-time game engines to high-quality renders. It relies on clean, manifold base surfaces to function correctly and supports both stylized and realistic character styles.
