QuadSketch V2.0.0 — Blender Retopology Quick Start Guide

QuadSketch is an interactive Blender retopology add-on for creating, extending, connecting, and refining clean quad topology directly over complex source meshes while maintaining direct control over topology flow.

Requirements

• Blender 4.2 or newer
• Tested with Blender 4.2 and Blender 5.2.2
• Windows, macOS, and Linux

Installation

1. Open Blender.
2. Go to Edit > Preferences > Add-ons.
3. Choose Install from Disk.
4. Select QuadSketch_v2.0.0_Blender_4.2_Plus.zip.
5. Enable QuadSketch.
6. Open the 3D Viewport and press N.
7. Open the QuadSketch tab.

Getting Started

1. Select your high-resolution source mesh.
2. Click Set Source in the QuadSketch panel.
3. Use Start Retopo to begin creating topology from drawn strokes.
4. Continue building and refining the topology using the tools that best suit each area of the model.

Main Tools

• Start Retopo

Draw strokes directly over the source mesh to generate clean quad-based topology with adjustable strip resolution.

• Guide Strip

Create controlled quad strips across complex surfaces while defining direction, width, resolution, and continuity with surrounding topology.

• Vertex Surface

Create and extend topology with precise vertex-based control in tight, curved, or complex areas.

• Draw Patch

Create quad patches directly over the source surface and control the number of rows and columns interactively while drawing.

• Contour Loop

Create controlled topology loops around cylindrical or rounded forms with interactive segment control.

• Circular Cap

Create clean quad-based caps for compatible circular boundary areas.

• Extend

Continue existing topology from selected boundaries while following the source surface.

• Stitch Edges

Connect compatible boundary edges between separate topology patches to build a continuous surface.

• Weld Vertex & Weld Edge

Merge compatible vertices and topology edges during the retopology workflow.

• Refine Brush

Smooth and refine topology directly over the source surface while preserving the overall structure.

• Move Brush

Interactively reposition and adjust topology over the source surface for local shape and flow refinement.

• Loop Edit & Tools

Insert, remove, smooth, relax, and optimize topology loops.

• Viewport Controls

Customize Diffuse Color and Surface Opacity for improved topology visibility while working.

Documentation & Training

QuadSketch includes built-in access to its video training and PDF documentation directly from inside the add-on.

Support

If you encounter an issue, please include your Blender version, QuadSketch version, a short description of the problem, and a screenshot or video when possible.
