Quick Metal Materials (QMM) is an add-on that creates a dedicated panel in the 3D Viewport sidebar, allowing you to assign a variety of metal materials to selected objects with a single click. For alternative workflows, the material library is also provided as a standard Asset Browser file and a KPACK for KitOps integration.

The package also includes the Quick Material Colors add-on, which applies custom colors directly to a material node's base color. This color library contains over 1,925 presets categorized for use on buildings, interior walls, automobiles, military equipment, and household appliances.
