Why we like it

UV King earns its place in the Blender library by pairing one-click packing with manual control over how islands are grouped, scaled, rotated, and placed. A demo video is available.

What is Uv King - Smart Uv Packing?

UV King - Smart UV Packing is a UV packing addon for Blender that unwraps, organizes, and packs UV islands. You can pack everything with one click, or fine-tune how islands are grouped, scaled, rotated, and placed. It's built to handle both simple models and heavy production assets, packing thousands of UV islands with smarter use of texture space.

The addon includes heuristic packing that tries different layouts to find the best result, auto unwrap presets for different model types, and manual rotation tools that rotate UVs by 90° or 45° while keeping them inside the UV space. UV Transfer copies UV layouts between identical meshes, and 3D-aware alignment orients UVs based on their real 3D orientation. It also works across multiple UDIM tiles, stacks identical UVs automatically, controls packing using groups, and adjusts texel density.

UV King is compatible with Blender 4.0 through 5.1 and runs on Windows, macOS, and Linux. It works with the Cycles and Eevee render engines and is distributed under the GPL license. After unwrapping a mesh, you select your UVs, adjust a few optional settings, and click Pack.

Frequently asked questions

Does UV King work with Blender 4.0 and later?

UV King - Smart UV Packing is built for Blender 4.0 and above, with listed compatibility spanning Blender 4.0 through 5.1. It's a Blender-compatible extension of the add-on type, and it works with both the Cycles and Eevee render engines. If you're running a Blender release inside that range, the addon fits into your existing workflow after unwrapping a mesh.

Does UV King run on macOS and Linux?

UV King runs on Windows, macOS, and Linux, covering the three main desktop platforms Blender artists work on. That cross-platform support sits alongside its Blender 4.0 through 5.1 compatibility, so the same packing tools are available regardless of your operating system. The workflow stays the same across platforms: after unwrapping, you select your UVs, adjust a few optional settings, and click Pack. For any platform-specific installation notes, refer to the developer's page.

Does UV King support UDIM workflows?

UV King - Smart UV Packing works across multiple UDIM tiles, making it suitable for film and VFX assets that rely on UDIM layouts. Alongside UDIM support, it can automatically stack identical UVs, control packing using groups, and maintain or adjust texel density. It also packs thousands of UV islands at once with smarter use of texture space. These tools cover both game-ready assets and high-resolution UDIM layouts, so the same addon spans a range of project types.

How do I pack UVs with UV King?

UV King fits into your Blender workflow after you've unwrapped a mesh. Select your UVs, adjust a few settings if you want to, then click Pack, and the addon handles the rest with no complex setup needed. You can pack everything with one click, or fine-tune how islands are grouped, scaled, rotated, and placed. For maximum efficiency, its heuristic packing tries different layouts to find the best possible result. A demo video is available if you want to see the steps.

Is UV King free, and what license does it use?

UV King - Smart UV Packing is listed as free in this catalog. It's distributed under the GPL license as a Blender add-on. Because pricing and licensing terms can change, check the developer's page for the current details before you download.
