3d-metal-material

separate

Build hyperrealistic PBR metal in Three.js: steel, brass, gold, copper and iron as true conductors (metalness 1, measured F0 tint, no albedo) with roughness-varied finishes (polished, brushed anisotropic, aged with patina and worn edges) lit by a dark HDR studio of real bright window cards prefiltered with PMREM. Use when metal looks like grey plastic, a dull blur, or a black hole; when blades, tools, rings, ingots, hardware or product metal need reflections with edges and structure; or when a finish needs scratches, streaks, fingerprints and bevels that catch light.

When to use

• steel, brass, gold, copper and iron materials
• polished, brushed anisotropic, and aged finishes
• blades, tools, rings, ingots, hardware, and product metal
• scratches, streaks, fingerprints, and bevels
• dark HDR studio environment setup
• PMREM prefiltered lighting

When not to use

• one bright edge catch and halo on a product
• authored PBR texture sets with texel density and mip budgets
• water materials
• wood, cloth, and paper materials
