Changelog

Release highlights, newest first. The complete changelog ships with the add-on in CHANGELOG.md.

v3.0.2 — Bug fixes

• Checker Map visibility — enabling the checker now switches the 3D viewports to show the texture (Solid shading → Color: Texture), so it's visible even when your material isn't set up for it; your shading is restored when you turn it off.
• Island tools respect your UV selection with sync off — on Blender 5.0, Rectify and the other island tools now affect only the island(s) you selected in the UV Editor, whether UV/mesh sync is on or off.

v3.0.0 — Public launch

• First public release of TexelPack. No packing-engine changes since v2.19.0 — this milestone consolidates the product, full documentation and support.
• Complete user documentation — this site (landing + docs in English, Spanish, Portuguese and Simplified Chinese) plus a Markdown guide that ships with the add-on.
• Support — a published support email and updated documentation links.
• Verified against real Blender 3.6, 4.2 and 5.x builds.

v2.19.0 — Redesigned UI with category rail

• A single panel with an icon rail that switches between 7 categories (Pack, Islands, Layout, World, Texel Density, Export, Presets) — far less scrolling.
• Show All toggle at the top stacks every section in one scroll, for those who prefer it.
• The previous three panels are consolidated into one; no controls were lost.

v2.18.0 — World-aligned UVs & orientation

• Project from World — box/triplanar projection from world space at your texel density; the checker stays continuous and new geometry continues existing islands.
• Orient to World — rotate islands so world up reads as up in the UV.
• Orientation checker — a Color Grid checker option that reveals island orientation and mirrored UVs (the plain grid is symmetric).

v2.17.0 — Rectify, real-shape SVG & multi-language UI

• Rectify Islands — flatten curved quad-grid islands (tubes, pipes, vases) into a straight rectangle. Works on the open UV strip, so closed surfaces rectify cleanly.
• Real-shape SVG export — the UV layout SVG now draws one polygon per face (the real island shape), not bounding-box squares.
• Multi-language UI — English, Spanish, Portuguese and Simplified Chinese, with an add-on language override that doesn't change Blender's own language.

v2.16.0 — Texel density & layout tools

• Get / Set Texel Density — read the density of the active island and scale the selection to match it.
• Align & Distribute islands — align to the selection bounds and distribute with equal gaps (horizontal / vertical).
• Orient to Edge — rotate each island so a chosen UV edge becomes horizontal or vertical.
• Checker Map — apply/remove a UV grid texture to inspect distortion, restoring original materials afterwards.

v2.15.0 — Smart selection & Pack Selected

• Select Similar / Flipped / Border / Invert at the island level.
• Pack Selected — pack only the chosen islands into the free space, leaving the rest in place.

v2.14.0 — Interactive Island Tools

• Stack / Unstack, Flip X / Y (per-island pivot) and Straighten, without a full repack.

v2.13.x — Stacking, lock, groups & destinations

• Stack identical and mirrored islands (with a similarity tolerance), lock intentionally overlapping islands, group packing by object/material/collection, and pack to a specific tile or region.
• Python API documentation and a headless batch driver.

v2.11.0 – v2.12.0 — Shape-aware packing & speed

• Mask-based Max Quality packing by real island shape; island straighten; anytime search.
• Vectorized (numpy) island extraction for heavy meshes.

v2.0.0 – v2.9.0 — Analysis & workflow

• Texel density and UV distortion overlays, coverage report, SVG layout export, presets, modal progress, pixel-grid alignment, preview-before-apply, Max Quality mode and excluded regions.

v1.x — Foundations

• The three core algorithms, arbitrary rotation, multi-object packing, pinned islands, UDIM support and per-island margins.
