UV Unwrapping: Smart UV Tool

Smart UV Tools One-click unwrapping with pro-grade control, when you need it.

Unwrap any mesh in one click, see exactly where your UVs stretch before you texture, and pack with real texel density — all from a single panel. No manual seam-marking marathons, no guesswork.

Good UVs shouldn't take longer than the model did Blender's native unwrap gets you 80% there and leaves you to manually mark seams, eyeball stretching, and repack by hand — every single object, every single project. Smart UV Tools automates the part that's tedious (seam detection, island packing, texel density) while still giving you full manual override when a specific island needs a human touch.

Pro packing power, without the pro-tool learning curve Dedicated packers like UVPackmaster and full toolkits like Zen UV are excellent — and built for riggers who live in the UV Editor daily. Smart UV Tools is built for the rest of us: one panel, sensible defaults, and a mesh classifier that tells your seams and unwrap method whether it's looking at a hard-surface prop or an organic character, without you flipping a single setting.

What's inside One-Click Full Mesh Unwrapping Select your mesh, hit unwrap, done. Smart UV Tools reads the geometry, places seams, and unwraps in a single operation — built for the 90% of objects that don't need hand-holding.

Real-Time Stretch Heatmap See distortion before you ever open the UV editor. Green means your texture will map cleanly, red flags where it'll stretch — so you catch problems while you're still looking at the 3D viewport.

Mesh Classifier & Smart Solve Smart UV Tools tells organic surfaces apart from hard-surface geometry and adjusts its unwrap strategy accordingly. Smart Solve then resolves problem islands automatically instead of leaving you to manually hunt down every stretched face.

Texel Density & Margin Presets Set a target texel density once and match every island to it, or drop in a margin preset tuned for your target texture resolution — no more manually calculating px/m by hand.

UDIM Support Work across multiple UDIM tiles for high-resolution, multi-material assets, with packing that respects tile boundaries automatically.

Symmetry Detection & World-Axis Orientation Mirrored geometry gets recognized and stacked automatically to save texture space, and islands can be oriented to world axes for perfectly straight, easy-to-paint textures like brick, wood grain, or signage.

Seam Suggestion System Get intelligent seam placement suggestions based on edge angle and geometry, then accept, tweak, or override them by hand — you stay in control of the final result.

Built for Game artists who need consistent texel density across an entire asset set Prop & environment artists unwrapping dozens of objects per scene Character artists who need clean organic unwraps without manual seam marathons Freelancers & solo devs who want pro results without a pro-tool learning curve Requirements Blender 4.2 or newer (packaged as a Blender Extension) Windows, macOS, and Linux supported Installation Edit > Preferences > Get Extensions > Install from DiskSelect the downloaded .zipEnable "Smart UV Tools" in the Extensions list Licensing Plan Includes Price Personal 1 user, all features, lifetime updates [$20] UV unwrapping Blender addon · one click unwrap · UV stretch heatmap · texel density Blender · UV packing addon · UDIM support Blender · auto seam generator · seam suggestion Blender · symmetry detection UV · world orient UV islands · organic mesh unwrapping · hard surface UV mapping · UV editor addon · game asset UV mapping · Blender 4.5 UV addon · Blender 5.0 extension · UV margin presets · UV island packing · character unwrap Blender · prop texturing UV workflow
