Model Sets (Pro feature) allow you to save independent Scene Tree variations in a single .bip file.

The Model Sets interface is located in the Project > Scene tab as a sidebar on the left side of the panel.

When a Model Set is selected in the sidebar it’s properties will be displayed in the sub-tab below and the contained Models will be listed in the Scene Tree.

• Show/hide Visibility of Model Sets can be toggled via the checkbox in the sidebar or by right-clicking and selecting Make Model Set Active. More than one Model Set can be active at a time.
• Switch Double-clicking a Model Set in the sidebar will make it active and deactivate all others (except Always Visible).
• Lock/Unlock Locking a Model Set will lock all contained models and parts.
• Reorder Model Sets can be reordered by drag-and-drop in the sidebar list.
• Rename Model Sets can be renamed via the right-click menu in the sidebar or in the Model Set properties sub-tab.
• Always Visible Model Sets can be set to Always Visible via the right-click menu in the sidebar or in the Model Set properties sub-tab. This will hide the checkbox in the sidebar. This is mostly useful for staging geometry such as a ground plane or props.

Adding Model Sets

A new Model Set can be added by clicking the  Add Model Set icon above the Model Sets sidebar, which will launch the Add Model Set dialog. Here you can give the new Model Set a name. In the list of Models (in the bottom of the dialog) you select what to clone into the new Model Set and the checkbox options enable you to  specify what to include from the selected Model Sets. By default the visible Model Sets will be pre-selected.

You can also access this dialog by selecting the models/parts in the Scene Tree you wish to include in the new Model Set > right-click and select Create Model Set from Selection.
