Quick start
Pack a tight atlas in under a minute. The defaults are tuned for everyday use — you only reach for the advanced panels when you need them.
1. Select your objects
Select one or more mesh objects that already have UV maps. TexelPack packs the whole selection into a single shared atlas in one operation.
2. Open the TexelPack tab
Open the UV Editor, press N to reveal the side panel, and switch to the TexelPack tab.
3. Pick a size and pack
Choose an atlas size (in pixels) and click Pack UVs. That's it — your islands are packed and your UVs updated. Ctrl+Z undoes the operation like any other Blender action.
Not sure about the result? Use Preview instead of Pack to see the layout in the UV Editor first — confirm with Enter or discard with Esc without touching your UVs.
Finding everything: the category rail
The panel has an icon rail down the left side that switches between categories, so you only see one section at a time instead of scrolling through everything:
- Pack — atlas, algorithm/quality, rotation, and the advanced options (normalize, UDIM, groups, destination, excluded regions).
- Islands — stack, flip, straighten, rectify and smart selection.
- Layout — align, distribute and orient.
- World — project from world and orient to world.
- Texel Density — get/set density, the overlays and the checker map.
- Export — last-run stats, SVG and JSON/CSV export.
- Presets — save and load configurations.
Prefer to scroll? Tick Show All at the top of the panel to stack every section in one column.
Reading the result
After packing, the Export category reports packing efficiency, the texel-density range and the overlap count. Click Copy report to put a text summary on your clipboard, or export per-island data — see Workflow & export.
Next steps
- Packing tighter: choose an algorithm and tune rotation, stacking and margins.
- Consistent resolution: normalize texel density and use the overlays.
- Automating: drive TexelPack from Python or batch-process .blend files.
