Why we like it

TexelPack earns its place in the superhive library for its texel-density workflow: normalization and overlays combined with shape-aware packing, with efficiency and overlaps measured on real geometry rather than bounding boxes.

What is Texelpack?

TexelPack is a UV packing add-on for Blender built around texel density. Blender's native Pack Islands arranges UVs, but it doesn't give every surface a fair share of texture resolution, doesn't pack by real island shape, and offers no visual feedback on density or distortion. TexelPack handles all of this from a single panel: it normalizes texel density across a whole selection, packs by the real shape of each island, and lets you see the result before you bake.

It scales each island to the real 3D surface area of its object, including object scale, so a big crate and a small prop get consistent resolution at a target density in pixels per meter. Four packing modes — MAXRECTS, Guillotine, Shelf and a shape-aware Max Quality mode — cover different layouts, while color-coded texel-density and distortion overlays make problems obvious in the viewport. Island tools, world-aligned UVs, multi-object atlases, UDIM and group packing round out a production-oriented feature set.

TexelPack works on Blender 3.6 LTS, all of 4.x and 5.x, with no external dependencies. A demo video is available.

Who is Texelpack best for?

Texelpack is best for 3D game artists, environment artists, hard-surface modelers and indie studios who care about consistent texture resolution and tight atlases.

How much does Texelpack cost?

Texelpack is completely free to download and use.

Key features

  • Uniform texel density: scales each island to the real 3D surface area of its object, object scale included, at a target density set in pixels per meter
  • Four packing modes: MAXRECTS, Guillotine, Shelf, and a shape-aware Max Quality mode that packs by the real rasterized shape so small pieces slot into the holes of larger ones
  • Visual overlays: color-coded texel-density and UV-distortion maps in the 3D viewport, so problems are obvious before baking
  • Island tools: stack/unstack identical or mirrored islands, flip, straighten, rectify curved quad grids, and smart selection by similar, flipped or border
  • World-aligned UVs: project UVs from world space at a target density and orient islands to world up
  • Production features: multi-object packing into one atlas, UDIM, group packing per object, material or collection, pinned islands, per-island margins with pixel-exact padding, excluded regions, presets and a copyable pack report
  • Export and automation: per-island data in JSON/CSV, real-shape SVG layout export, a pure-Python packing API, and a headless batch driver for whole .blend libraries

Frequently asked questions

Does TexelPack work with Blender 5.x?

TexelPack works on Blender 3.6 LTS, all of the 4.x series, and 5.x. It ships in both the modern Extension format for 4.2 and later and the legacy add-on format for older builds, so you can install it whichever way suits your version. Every release is smoke-tested against real Blender 3.6, 4.2 and 5.x builds and backed by an automated test suite of over 1300 tests.

Does TexelPack need any external dependencies or pip install?

TexelPack has no external dependencies and runs entirely on Blender's bundled Python, so there is nothing to pip install. Analysis and packing run in a background thread, which keeps the interface responsive, and you can cancel with Esc. This non-blocking design means the UI stays usable while it processes. Full user documentation covering installation, quick start, per-feature guides, FAQ and troubleshooting ships with the add-on and is also available online, so setup and reference material are close at hand.

What languages is TexelPack available in?

TexelPack is fully translated into English, Simplified Chinese, Spanish and Portuguese, covering the entire interface, panels, buttons, tooltips and pack reports. A built-in language switch lets you change the add-on's language independently of Blender's own UI language. Its documentation, spanning installation, quick start, per-feature guides, FAQ and troubleshooting, is available online in English, Spanish, Portuguese and Simplified Chinese and also ships with the add-on, so teams working across those languages can use both the tool and its guides in their own language.

How does TexelPack pack UVs compared to Blender's Pack Islands?

TexelPack includes a shape-aware Max Quality mode that packs by the real rasterized shape of each island, so small pieces slot into the holes of larger ones, alongside MAXRECTS, Guillotine and Shelf modes. Efficiency and overlaps are measured on real geometry rather than bounding boxes. Packing supports multi-object atlases, UDIM, group packing per object, material or collection, pinned islands, per-island margins with pixel-exact padding and excluded regions, and a preview lets you check the result before applying it to your mesh.

What license is TexelPack under, and can I use it commercially?

TexelPack is licensed under GPL-3.0-or-later, as required for Blender add-ons. You can use it on any number of machines for both personal and commercial projects, with no per-seat restrictions. Support is provided by email, and all future updates are included. This entry is listed as free in our catalog; for current licensing details, check the developer's page. The GPL terms make it straightforward to deploy the add-on across a whole studio.
