User Interface
The UVPackmaster UI is located in the N panel of the UV editor, in the UVPackmaster4 tab:
The UVPackmaster UI is split into a set of multi panels:
You choose which multi panels to show by using toggles on the top in the Main panel. Every toggle drives a single multi panel. You can press a toggle with Shift in order to enable more than one multi panel at a given moment. Contents of currently selected multi panels are displayed in the Main panel.

Multi panel settings
In the first panel header of every multi panel, you will find an icon allowing to access a given multi panel settings:
The multi panel settings currently provide one option: Display Mode. The option determines how a given multi panel is displayed in the UI. Available values are:
-
Embedded (default value for every multi panel) - the multi panel is displayed as a toggle in the Main panel in the UVPackmaster4 tab (alongside all other multi panels with Display Mode set to Embedded). When the multi panel toggle is selected, the multi panel contents will be displayed in the Main panel:
-
Detached - the multi panel is displayed as a separate panel in the UVPackmaster4 tab (outside the Main panel):
-
Tab - the multi panel is displayed in its own tab in the N panel of the UV editor (outside the UVPackmaster4 tab):
Note: after changing multi panel settings, one needs to save Blender preferences in order to make the change permanent (available after reopening Blender).
Subpanels
Certain panels in the UI provide subpanels allowing the user to enable certain features. By default, all available subpanels of a given panel are always displayed and the user can enable a given subpanel using the checkbox in the given subpanel header. For example, that’s how the subpanels of the Advanced Packing Options panel look like:
The method of displaying subpanels can be changed using the Subpanel Mode global option in the Preferences multi panel. When the option is changed from Standard to Enable Menu, the packer will not display all subpanel under a given panel anymore. Instead it will display a menu at the bottom of the given panel allowing the user to enable certain subpanels (features). Then only the currently enabled subpanels (features) will be displayed under the panel.
That’s how the Advanced Packing Options panel looks like after Subpanel Mode is set to Enable Menu:
By expanding the menu, the user can select a subpanel to enable:
Only enabled subpanels are then displayed under a panel. The user can disable (close) a given subpanel by pressing the Cross button in the subpanel header:
