The Result

The result is a new object, <name>_quadguide, in place of the original. Before it is shown, it is checked: all quads, no holes, nothing inside out, the same openings as the original.

The verdict at the bottom left of the viewport reads clean, or says what needs a look.

A Few Quads May Need a Touch-Up

Thin parts, such as an ear rim or a fingertip, can leave a few pinched quads. Select Problem Quads (F3 search) selects them in Edit Mode; Blender's Relax brush fixes them. If it keeps happening, raise Quads or paint the part Denser.

Keep or Discard

When a new result has problems and a good one already exists, the new one arrives as a candidate next to it. Keep uses the candidate; Discard deletes it.

Update after Moving a Guide

After a guide is moved, Update (N regions) appears above Remesh. It remeshes only the regions next to that guide, tinted orange in the viewport; the rest keeps its vertices. It needs a result made with Fill with Patches on.

Review

With Expert Settings on in the add-on's preferences, a Review list under the result shows the quad count, the poles, the spread of quad sizes and any open edges. To see poles and sizes on the mesh, turn on Poles and Density under Options.

Save Report

The export icon next to the result line saves a zip of the run, mesh included, for a bug report. See Reporting a problem.
