Nitro Retopo

Adriflex in Modeling


A new way to clean up
and retopologize your mesh.

Segment. Repair. Draw your topology.

Turn dense meshes with fused parts into editable pieces. For AI-generated models, sculpts, 3D scans, and other meshes that need cleaner topology.

Featured on: 80 Level · ModelingTechNote · CGbox

New in 1.4: preserve your cuts while simplifying, open individual boundaries with J, and delete patches with X.

A simpler start for dense meshes.

Prepare your mesh in one click. Nitro Retopo uses Blender's Decimate and automatically sets a reduction ratio suited to the workflow.

01 /  Draw the boundaries.

Build your patches with the drawing tools that suit each shape.

Curves, lines and freehand

Draw curved boundaries, sharp corners, straight lines and freehand strokes.

Ellipses and circles

Create an ellipse, constrain it to a circle and reposition it.

Follow existing edges

Trace a boundary along existing mesh edges.

Revise your boundaries

Erase boundaries to adjust the patch layout.

02 /  Edit your patches.

Separate parts, open a boundary or focus on the region you want to work on.

Split or delete a patch

Hold S and click to separate a patch. Hold X and click to delete it.

S separates a patch; X deletes a patch.

Open just one boundary

Hold J and click a highlighted cut boundary to open that section. The faces stay in the same object.

Hold J and click to open one cut boundary while keeping the faces in the same object.

Focus on what matters

Use Shift + H to isolate a patch, H to hide it, or hold L and drag to isolate several patches with a lasso. Alt + H reveals them again.

Isolate with Shift + H, hide with H and isolate several patches with the L lasso.

03 /  Simplify where you need it.

Brush over an area to reduce its local topology. Enable Preserve Cuts to keep the cut boundaries and connections you have already drawn.

Local Simplify Topology, first without Preserve Cuts, then with Preserve Cuts enabled.

04 /  Repair the gaps.

Fill holes or bridge open boundaries, and adjust the shape before applying.

Interactive patch repair: fill a hole, adjust the surface and bridge open boundaries.

05 /  Choose how the topology flows.

Define the corners

Mark patch corners to guide the generated topology.

Explore patterns and insets

Cycle topology patterns, change their orientation and add an inset.

06 /  Your new mesh, ready to refine.

Drawn boundaries become seams. Generate a separate mesh with an automatic UV unwrap.
