Release 4.0.4

  • The entire UI code has been rewritten – the UI is now faster and more responsive.

  • Dynamic Tiles option: when UVs are packed with Dynamic Tiles on, the packer will automatically determine the number of target tiles to use – it will use as many tiles as possible to pack the UVs efficiently:

  • Better control over defining target tiles in the Tiles mode:

  • New group layout mode for texture atlas workflows:

  • Define texel density tiers: assign islands to tiers once, then modify texel density for them in tier settings at any time with no need for manual per-island reassignment.

  • Texel density operations now support fractional values.

  • Support for changing the texel density unit in the Preferences multi panel (global setting). Supported units are:

    • px/m (default value)
    • px/cm
    • px/in
    • px/ft.

    Every time you change the option value, the packer will automatically adjust all your texel density-related settings (values stored in presets, properties and per-island assignments in all blend files) to automatically match the new unit, so you don’t have to recalculate the values manually.

    After you change the unit, remember to save Blender preferences to make the change permanent.

  • Ability to use enable menus to determine which subpanels are currently displayed (feature limiting the number of subpanels displayed in the UI only to these which are currently enabled):

  • New variant of the UV aligning operation: Align To Unselected – aligns the selected islands on the top of the similar unselected islands:

  • New handy UI for editing target boxes as an overlay in the UV editor:

  • The Advanced Heuristic option now may take 3 values:

    • Automatic (Recommended) – the packer will automatically determine whether the Advanced Heuristic method is desirable for a given UV map,
    • Disable,
    • Enable.

    Automatic is always used by default.

  • Much faster heuristic search for the optimal result for UV maps with a limited number of islands (assuming Advanced Heuristic is set to Automatic).

  • Support for handy set menus for fast setting of certain per-island parameters:

  • Significant performance optimizations for certain types of very dense UV maps.

  • Performance optimizations for the Measure Area (Merged) operation.

  • The packer now reports islands with severely corrupted topology.

  • Fix the Adjust TD To Unselected operation.

  • Improvements for overlapping islands reporting.

  • Option to load only Pixel Margin settings from a preset file.

A lot of other functional, UI and user experience improvements, among others:

  • Moving the UI for grouping configuration to a separate Grouping (Packing) multi panel,

  • Improvements for grouping logic

  • Improving user experience in the Box Editing mode,

  • And other!

Release 4.1.1

  • Process your UVs with the AI assistant (without sending your 3D data to the cloud). Highly recommend reading the docs to learn how it works.
    Note this feature is disabled by default until the user explicitly enables it. After enabling, the assistant will only run when requested by the user – it will never run in background.
    What’s more the assistant may be useful even if you don’t want to use AI: the user with a basic coding knowledge may write their own assistant scripts which will process UVs according to their needs! The script may be then executed at any time without using AI. Visit the docs to learn more.
    AI assistant prompts and assistant scripts can be parametrized. More info in the docs.
    Below you can see a few examples of what you can do using the assistant:
  • The packer now properly ignores UVs of objects hidden in the 3D viewport.
  • The packer now properly honours the isolated display mode in the UV editor.
  • UV selection changes are now properly handled during operation undo and redo.
  • Many UI and UX improvements.
  • Fix for a rare unexpected error when using texel density features.
  • Names handled by the addon now support non-ASCII characters (grouping scheme names, group names, material names etc).
  • New operator Apply TD (Packing): apply per-island texel density (packing) values in place – without running an actual packing operation.
