For the UVPackmaster 3 release notes visit this page.

Release 4.0.0

  • 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.

  • Define individually where every multi panel is displayed in the UI:

  • 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):

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 4.0.1

  • Add support for Dynamic Tiles for Tiles, Groups Together, Groups Independently packing modes:

  • Object-related options have been moved from the N-Panel in Viewport to Object Properties:

  • Important fix for a bug which caused invisible faces to be affected by per-island parameter assignment.

Release 4.0.2

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

  • 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.

Release 4.0.3

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

  • Option to load only Pixel Margin settings from a preset file:
  • New transfer operations for quick moving from the UVPackmaster 3 to UVPackmaster 4 workflow:

    • Transfer V3 Options: transfers all options in the blend file from the UVPackmaster 3 addon to the UVPackmaster 4 addon,

    • Transfer V3 Object Data: transfers object data for the selected objects from the UVPackmaster 3 addon to the UVPackmaster 4 addon (including grouping schemes and per-island parameters).

  • Transfer operators are available in the Other Tools multi panel:

  • The Remove UVPM Data From Object operator now also removes all UVPackmaster 3 data.

  • Minor bug fixing.

Release 4.0.4

  • 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:

  • 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.

  • Fix for heuristic search with both Fixed Scale and Dynamic Tiles options enabled.

  • Misc bug fixing.
