Ensure you are running Blender 5.0 or newer — Ultra will not load on Blender 4.x. Go to Edit → Preferences → Extensions and confirm that Quadify Ultra is listed and enabled. If the extension is enabled but the panel is missing, try disabling and re-enabling it, then restart Blender.
Non-manifold geometry — including T-junctions, internal faces, and boundary edges — can cause unexpected results with all algorithms. Before running Quadify, go to Mesh → Clean Up → Merge by Distance to close near-duplicate vertices, and Mesh → Clean Up → Delete Loose to remove floating geometry. For complex non-manifold issues, use Select → Select All by Trait → Non-Manifold in Edit Mode to identify problem areas.
QuadriFlow + Transfer and Voxel Remesh + Transfer modes cannot preserve shape keys, since the geometry is replaced entirely. You will see a warning if shape keys are detected. Bake shape keys to separate meshes before using these modes if you need to preserve them. The Smart algorithm does not replace geometry and is safe to use with shape keys.
A warning appears when a Mirror modifier is detected on the selected mesh. For best results, apply the modifier to one half of the mesh, process it with Quadify, then re-apply the mirror. Processing a mirrored mesh without applying the modifier first can cause seam artefacts at the mirror boundary.
If QuadWild times out, try a lower resolution preset (Draft or Medium) or reduce the mesh face count before processing. On meshes above 20,000 faces, auto-decimate runs automatically before QuadWild — if it is still timing out, manually decimate the mesh further using a Decimate modifier before running Quadify.
The Instant Meshes algorithm requires the binary to be configured in Settings. Go to the Settings panel, find Instant Meshes Binary Path, and set it to the path of the Instant Meshes executable on your system. Instant Meshes is not bundled with Quadify Ultra and must be downloaded separately.
The ML system requires approximately 30 operations before recommendations reflect your specific mesh types. If routing recommendations seem off early on, override them manually — each correction is recorded and helps the model learn. You can also download the community model from Settings to start with a larger baseline dataset.
