Metal materials from a reflectance table
In your harnessBlender toolMIT
Build a fully metallic Principled material for gold, silver, copper, aluminium, iron, titanium, chromium, nickel, platinum, zinc, brass or cobalt from a table of approximate normal-incidence reflectance values, with roughness variation and optional brushing. Use it for jewellery, hardware and props.
What it takes and gives
- Operator
- baltor.material_metal_f0_library
- Parameters
- metal, roughness, roughness_variation, brushed, assign
- Result
- One metallic material named Baltor and the metal name; assigned to the active object.
- Blender
- 4.2 or later
- Axes
- Blender Z up, -Y forward
- Units
- metres
Limits. The F0 values are approximate linear sRGB reflectances rounded to two decimals; the edge tint of real metals is left to the Principled BSDF's default model, and oxidation, patina and scratches are not included. Brass and similar alloys vary with composition. Brushed anisotropy needs tangents that follow the brushing direction. Rendered here with Cycles CPU only. Verified in Blender 5.2.1; written for the 4.2 API.
