Material Switch 2 is a workflow add-on that helps manage and swap material setups for mesh objects. It adds a dedicated side panel to the 3D Viewport where users can organize existing project materials into distinct groups called switches.

Once a switch is assigned to an object's material slot, users can quickly alternate between the materials stored within that switch. This setup eliminates the need to manually reassign materials from the properties panel, allowing for rapid visualization and comparison during look development.
