QuadSketch – Interactive Retopology for Blender

QuadSketch is a workflow-focused retopology add-on for Blender, designed to make creating clean quad topology faster and more interactive.
Draw directly over your source mesh, guide edge flow, build and extend surfaces, connect separate topology patches, refine your mesh, and manage loops—all within a streamlined retopology workflow.
Built for character, creature, and organic modeling, QuadSketch gives artists direct control over topology while staying close to the original surface.

• Start Retopo — create quad topology directly from drawn strokes.
• Guide Strip — build controlled quad strips and define clean edge flow across complex surfaces.
• Vertex Surface — create and extend topology with precise vertex-based control.
• Extend — continue existing topology while following the source surface.
• Stitch Edges — connect separate topology patches into a continuous mesh.
• Weld Vertex & Weld Edge — merge and connect topology efficiently.
• Refine Brush — smooth and refine topology directly on the surface.
• Loop Edit & Tools — insert, remove, smooth, relax, and optimize topology loops.
• Symmetry Workflow — speed up retopology on symmetrical models.
• Patch Workflow — build larger retopology projects in manageable sections.
• Topology Statistics — monitor vertex and polygon counts directly in the QuadSketch panel.
• Viewport Controls — customize topology color and surface opacity for better visibility.

Requirements

• Blender 4.2 or newer
• QuadSketch v1.0.0
