Understanding PolyGroups
PolyGroups are groups of polygons that share a unique color. A PolyGroup can be selected, isolating it from the rest of the mesh (3D model) by hiding the remaining PolyGroups. This makes it easier to modify the model without affecting parts of it accidentally. It is especially helpful when working on specific parts repeatedly, as it saves time.
The division of your mesh into PolyGroups is relevant for a variety of tools and operations. Some of these will be covered in later chapters, but by far the most common use is to hide part of the mesh for a more convenient modeling or sculpting experience.
Important note
You can see the PolyGroups by pressing Shift + F or enabling Polyframe by hitting the PolyF button in the Transform palette.
The following screenshot shows how a complex armor on a 3D character is made up of many PolyGroups, allowing you to isolate parts and work on them conveniently:
