metals (Forge and Patina)

The materialLibraryKit collection inside metalsMaterials: 28 metal materials with tags. They cover steel, iron and rust, aluminium and anodised colours, copper, brass, bronze, gold, silver, painted metal, three toon metals and a hand-painted iron. Each entry comes with:

• category: metal, plus a kind and a style;
• the real-world tileSize in metres;
• the roughness and metallic ranges it actually renders with;
• its measured textureKB;
• animated: false;
• search words.

The core lists this collection under the name metals:

local Materials = require("~materialLibraryKit.Materials")
Materials.list({ collection = "metals" })       -- all 28
Materials.list({ category = "metal", tag = "rusted" })

MetalCatalog.build() generates collection.yaml. Don't edit it by hand: change the metal's entry in MetalCatalog and rebuild.
