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 ColorPick objects, pick a color — the material color is set directly from a color picker, no panel digging.
• Match Identical MaterialCopy one object's full material — color, gloss, transparency, every map — onto the objects you select.
• Synchronize Render ColorMake the material color match the display color, so the render looks like the viewport you approved.
• Set Material Source: LayerSelected objects take their material from their layer again — the reset for per-object material chaos.
• Merge IdenticalFind materials with identical settings, keep one, delete the rest — assignments update themselves.
