You can create sets of selected components for your model so you can quickly select the items together later.
For example, you can create a selection set for faces in a particular region of a model so you can freeze and unfreeze them repeatedly as you work. A selection set lets you define this region as a custom selection.
In addition, if you’ve combined a number of polygon meshes into one model prior to importing to Mudbox, it can be difficult to select the various components. Creating a selection set lets you easily select those regions on the combined model in Mudbox.
In Mudbox, selection sets appear in the Object List and are saved with the model as part of the .mud file.
The selection set appears in the list of items within the Object List.
