3ds Max Retopology
This is what my team has been working on lately. We have a new retopology modifier that allows you to use the Instant Mesh, Quadraflow or our own ReForm algorithms to retopologize your mesh.
We also have a Mesh Clean modifier that cleans out degenerate edges/faces and Non-Manifold geometry.
With 2021.3 we have also update the subdivide modifier with 3 new algorithms. Delaunay, Adaptive and Variable Curvature. Hope you guys like it!
