NEW IN 2.0.0

From raw AI mesh
to clean topology.
Now for Blender 5.3

Retopia 2.0 adds a full Sculpt Prep toolkit for AI-generated meshes and scans — slice them into parts, repair holes, keep heavy meshes fast — and introduces Guided Patches: draw a network of lines and every region fills with clean quads at once.

SCULPT PREP SPLIT CUT PATCH REPAIR GUIDED PATCHES · BETA

SCULPT PREP · NEW

Split Cut

Click points on the sculpt around a part — they stay on the surface when you orbit. Close the line and the mesh is sliced through the faces, exactly where you drew. It stays one mesh, opened along the cut, and every part gets its own colour. Select Part picks a part to move or delete it; Separate into Objects when you want real objects.

SCULPT PREP · NEW

Patch Repair

Works right on the open border. Click where you start, follow the border, click where you stop — a live preview shows the new surface before anything changes.

▸ One part of a border: filled up to a straight line.

▸ Two parts: a bridge between them.

▸ Ctrl+click a whole border: the hole is closed — two whole borders are joined by a tube.

▸ Density and Keep Curvature change the preview live; clean quad grids wherever the border allows.

SCULPT PREP · NEW

Make Light Copy

Millions of faces? Work on a lighter copy, like ZBrush Decimation, with a progress bar while it builds. Every tool stays fast, the original is never touched, and you switch between Original and Light Copy at any time.

Check Sculpt — faces, loose parts, holes, non-manifold edges and inverted normals at a glance. Nothing is changed.

Fill Holes — closes the holes of the light copy, so the tools never fall through.

Rebuild Area — click around a broken area and it is rebuilt as a clean, even patch that follows the shape.

CREATE · BETA

Guided Patches

Draw an outline and the lines across it, in any order: every closed region is filled at once, with shared sides that always match. A live preview appears as soon as the network closes.

▸ Patterns — grids first; Y, star, T or split where a grid can't fit. Hover a region and press P to cycle the clean ones.

▸ Group per Region — every region gets its own face group and colour, ready for UV islands.

▸ Re-pattern — draw a line across a patch you already built: it splits exactly where you passed, keeps its outline, and both parts are rebuilt with clean quads — a grid first, other layouts with P.

▸ Lines snap onto your existing retopo, so new patches weld on by themselves.

VERSION 1.1 · FREE UPDATE

What's new in NKZ Retopia

Tubes drawn in one stroke, bands along any line, a live check of your topology and smarter face groups — plus a much faster viewport on dense retopo.

NEWCONTOURS

Spine

Draw one line along an arm, a leg or a finger: every ring of the tube is created at once, perpendicular to the limb and taken from its real cross-section.

• The tube starts and ends exactly where your line does.
• Start a line on the end of a tube to extend it — draw from one tube to another to join them. Ctrl: always a new tube.
• The same result from any point of view; end rings stay locked to the sculpt when you relax.

NEWSTRIP

Strokes

A new mode of the Strip: the line you draw becomes the centre of a band of quads, extruded evenly on both sides.

• Extend the line with more strokes, or close it on its start for a ring.
• Ctrl+Wheel for the width, Shift+Wheel for the divisions — the same keys as the Strip.
• Right-click to preview, right-click again to build.

NEWDISPLAY

Analysis

See the health of your topology at a glance, always drawn on top of everything else.

• Quality Map: every face coloured green, yellow or red by its angles, proportions and size.
• Show Poles: poles, triangles and n-gons highlighted.
• Select by count (Faces < 4 / > 4, Poles < 4 / > 4) and Select Bad Quads, ready for Relax.
• Target Faces: a polygon budget with a progress bar (mirror included).

IMPROVEDEDIT

Face Groups

Keep every part of the retopo readable with colour-coded groups.

• Auto Group: every new structure gets its own group the moment it's created.
• Group All: one click gives every structure a group of its own, with a unique ID.
• Each retopo object now keeps its own group list — older files are converted automatically.

VERSION 1.2 · FREE UPDATE

Three new finishing tools

NEWIN THE PIE MENU

Stitch Edges

Join two separate patches in two clicks. Pick a side, pick the side facing it, and NKZ Retopia bridges them with a row of quads — the whole side, corner to corner, however long or curved.

NEWTUBES & TIPS

Circular Cap

Close the open end of a finger, a horn or a claw: click the farthest tip and clean circular topology follows the real shape all the way there, ending exactly where you clicked. Ctrl+Wheel sets the rings.

NEWCLEAN-UP

Remove Loop

Too dense? Click an edge to light up its whole loop, right-click to remove it — the rows on both sides merge cleanly.

NEWPRECISE DRAW

Extend Border

Shift+drag from any border and the whole side grows new rows of quads that follow your mouse.

• Rows are laid over the sculpt one at a time, so the quads stay square even on curved surfaces.
• Drag sideways and the band leans with you.
• Rows are set automatically, or choose them with Shift+Wheel.

IMPROVEDLOOP & FILL

Fill Patterns

Click inside a hole and press Tab to switch the topology before you confirm.

• Grid, 3 Poles, 5 Poles and Fan: always clean, all-quad results.
• Small holes with an inner corner are refilled with exactly the faces you removed.
• Ctrl+Wheel: layout · Shift+Wheel: rotation · Alt+Wheel: inner rings · Right-click: confirm.

NEWDISPLAY

Subdivision Preview

See how your retopo will look once subdivided, live, while you work.

• The smoothed result is laid on the sculpt with even, undistorted lines.
• It stays inside the borders of your retopo, with your cage drawn on top.
• One click on or off, with 1–3 levels. Nothing is applied to your mesh.

NEWVERSION 1.4

Creation Animation

Right-click to confirm a preview and the new polygons settle into place with a short animation.

• 12 styles: Grow, Ripple, Sweep, Drop, Assemble, Pop, Sparkle, Spin, Flip, Tornado, Scatter and Bounce.
• Works with Draw, Strip, Edge Flow, Strokes, Contours, Circular Cap, Stitch Edges, Extend Border and Loop & Fill.
• Adjustable speed, or switch it off in Display.

NEWVERSION 1.4.18

A Redesigned Panel

The side panel now follows the way you work: Create, Refine, Organize, Finish.

• Status card: your retopo, its source, quads / tris / n-gons and symmetry at a glance.
• Big buttons for the main tools, so they are always easy to find.
• One options box that shows the settings of the tool you are using. A shorter, cleaner panel.
• Convert to Final Mesh: turn the retopo into a plain mesh, ready for the next step.

◆ ALSO IN THE TOOLKIT

Edge Flow — continue an existing row, perfectly matched.

Circle & Circle Loop — all-quad disks or rings for eyes, mouths and pipes.

Loop & Fill — create rings and fill holes with the cleanest layout.

Loop Cut and Knife — add loops under the mouse, plan several cuts and apply them at once.

Move, Conform, Merge, Align — the brushes and actions to tidy up any area.

Pins and Face Groups with Auto Group — lock what's done, colour-code what you build.
