Installation
Install on Blender 3.6 LTS, 4.x or 5.x — extension and legacy add-on formats.
Quick start
Pack your first atlas in three steps, then explore the advanced panels.
Packing & algorithms
Algorithms, rotation, stacking, UDIM, groups, destinations and margins.
By topic
- Interface overview — a tour of the panel's category rail and every control, with links to the in-depth guides.
- Packing & algorithms — the four packing modes, rotation, straighten, stacking, lock, group packing, destinations, excluded regions, margins and pixel alignment.
- Texel density & overlays — uniform texel density, the viewport overlays and honest statistics.
- Island tools — interactive stack/unstack, flip and straighten, plus smart selection.
- Workflow & export — preview, presets, the pack report, JSON/CSV and SVG export.
- Python API & batch — drive the packing engine from scripts and process whole `.blend` libraries headless.

Check the FAQ and Troubleshooting pages first. When reporting an issue, include your Blender version, the add-on version and reproduction steps (see License & terms for the support contact).
Compatibility note: every TexelPack release is smoke-tested against real Blender 3.6, 4.2 and 5.x builds. Where Blender's API changed between versions, TexelPack adapts automatically — see Troubleshooting for the details that matter to you.
