Release 3.3.1

First official release – provides the same set of features as UVPackmaster 3 for Blender.

Release 3.3.2

General improvements:

  • New variant of the pack operation: Repack With Others. Repack all selected islands with all unselected islands which are already placed in the target box:

  • New utility operator: Measure Area (Merged): measure merged area of selected UV islands (area of overlapping UVs will be added to the result only once):

  • Bug fixing.

Release 3.3.3

General improvements:

  • Support for a new packing paradigm Fixed Scale (Max Margin): packing with a fixed scale while searching for the maximum margin between islands:

  • The new mode can be selected using a new option Scale Mode (which replaces the old Fixed Scale option). It can be set to one of 3 values:

    • Max Scale (default):
      equivalent to Fixed Scale set to off in older versions
    • Fixed Scale:
      equivalent to Fixed Scale set to on in older versions
    • Fixed Scale (Max Margin):
      the new mode as presented above.
  • Ability to set the Scale Mode setting on a per-group basis in the Groups To Tiles mode using the overrides panel for a group.

  • Improvements for how the packing result is applied to the UV map when packing groups: starting from this version, the packer doesn’t wait for applying a result for a group until all groups are packed: instead it applies the result for a group immediately.

  • Fix for the Apply Grouping To Scheme operation.

  • UI fixes and improvements.

Release 3.3.4

General improvements:

  • New option Arrange Non-Packed Islands: when packing with fixed scale, arrange the islands that cannot be packed due to a lack of space in a line above the target UV area. The arrangement will be done after the operation is complete:

  • Performance optimizations for assigning per-island parameters.

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

  • Fix rare instabilities for the Orient UVs To 3D Space operation.

  • Bug fixes.

Release 3.3.5

General improvements:

  • Support for Maya 2026
  • Improving UI responsiveness when cancelling a heuristic search.

Bug fixing:

  • Fix for bug where not all info logs were displayed in the UI.
  • Fix for the Pack To Others operation.
  • Fix for undoing an operation sometimes not working properly.

Release 3.3.6

General improvements:

  • New option for the Split Overlapping feature – Don’t Split Priorities: when enabled, the packer doesn’t split islands sharing the same Align Priority value:
  • Support for overriding options on a per-group basis in the Groups Independently mode:
  • Ability to select / deselect islands by the assigned parameter value for all per-island parameters (e.g. Align Priority):

Bug fixing:

  • Fix a bug causing 3D geometry to be moved when undoing an operation under certain conditions.

Release 3.4.1

General improvements:

  • Significant performance optimizations for automatic grouping (by object, material etc).
  • Support for option sets. Using this feature the user can maintain different option sets within a single Maya file and switch quickly between them. Read the docs to learn more.
  • Ability to automatically set texel density before packing. Texel density value may be overridden on a per-group basis in a group-based packing mode (e.g. Groups To Tiles). Read the docs to learn more.
  • New operations in the Texel Density panel: Show TD and Set TD – display or assign texel density on a per-island basis, with visual feedback.
  • Improvements for the Arrange Non-Packed Islands option – islands are now arranged in many lines, not only in a single line, so they are placed closer to the UV space origin.
  • Improve logic of heuristic searching with Fixed Scale enabled.
  • Apply Grouping To Scheme now ignores objects with no selected faces.
  • The Adjust TD to Unselected operation has been moved from the Utilities panel to the Texel Density panel and now correctly calculates the actual texel density of islands.
  • Fix an error, when loading a preset saved with an old version of UVPM.
  • Miscellaneous UI improvements and fixes.

Release 3.4.4

General improvements:

  • Fix for a bug that prevented the packer from working when the UV editor was docked inside the Maya window.
  • New grouping method – group UVs by Vertex Color:

  • Performance optimizations for island stacking with Vertex Position and Topology modes.

  • Apply Grouping To Scheme now ignores objects with no selected faces.

  • Support for defining aligning target in the Pixel Perfect Align mode. Possible values are: Corner – align to pixel corners (the default behaviour), Center – align to pixel center points.

  • Ability to set Border Margin to 0. A separate checkbox was added to the UI for enabling the Border Margin feature. After enabling the feature, the Border Margin value may be set to 0 and the packer will apply this setting.

  • Support for a new grouping method: Collection – islands being a part of objects from the same outliner group will belong to the same UV group.

  • New option for the Normalize Scale feature: Normalize Groups – the option allows the user to define which islands should be normalized together. When enabled, the packer will perform the normalization operation independently per every defined group. For more info read this page.
  • Fix a bug causing the packer to output overlapping islands in rare cases for complex UVs.
  • Downloading Python dependencies is no longer required during packer installation.
