Sync

A model that has been through a real design process accumulates material clutter — colors that don’t match between viewport and render, near-duplicate materials, objects carrying their own material when the layer should decide. The Sync group is the housekeeping crew:

• Set Render ColorSets the material color straight from a color picker.
• Match Identical MaterialCopies one object's whole material onto the objects you select.
• Synchronize Render ColorMakes the material color match the display color.
• Set Material Source: LayerObjects take their material from their layer again.
• Merge IdenticalKeeps one of each set of identical materials and deletes the rest.
