Blender 2.81 development watch #1: retopology

Blender 2.81 adds new manual retopology features to the Poly Build tool. As a quicker alternative, the Voxel Remesh operator automatically generates a quad mesh based on the volume of a sculpt. Video: JayAnAm.

1. New retopology tools

Blender has some good third-party retopology add-ons, including RetopoFlow and newer contenders like DynRemesh and Tesselator, but Blender 2.81 aims to make it easier to convert dense 3D scans and sculpts into clean, animation-ready, all-quad geometry using only the software’s native tools.

For manual work, the Poly Build tool gets new retopology features. They make it possible to draw a quad mesh over the surface of a source sculpt, although it means working one quad at a time.

For automated work, the new OpenVDB-based Voxel Remesh operator generates a new all-quad mesh based on the volume of a source mesh. (It also works in Sculpt mode as a way of getting good topology when blocking out shapes without the performance hit associated with dynamic topology.)

A second automated remeshing system, the QuadriFlow library – also supported in DynRemesh – has also just made the cut-off for Blender 2.81. It’s slower, but has the advantage that the edge loops in the quad mesh it generates align to features in the source mesh, generating better-quality results.

Stay tuned throughout the rest of the week for bite-sized previews of other features, including new sculpting brushes, Open Image Denoise, and a host of time-saving smaller additions.
