Metallic Materials

Metal surfaces have high metallic values (0.9-1.0) and varying roughness. They reflect light strongly and have no diffuse component, making them appear highly reflective.

  • Metallic: 1.0
  • Roughness: 0.2-0.8
  • Base Color: Tinted reflections

Wood Materials

Wood is a dielectric material with low metallic values and moderate roughness. The grain patterns create natural variation in the normal and roughness maps.

  • Metallic: 0.0
  • Roughness: 0.6-0.9
  • Base Color: Natural wood tones

Fabric Materials

Fabrics are typically non-metallic with high roughness values, creating soft, matte appearances. Normal maps capture the weave patterns and fiber details.

  • Metallic: 0.0
  • Roughness: 0.8-1.0
  • Base Color: Fabric dye colors

Plastic Materials

Plastics range from matte to highly glossy. They're non-metallic but can have very low roughness values for shiny plastics, creating clear reflections.

  • Metallic: 0.0
  • Roughness: 0.1-0.7
  • Base Color: Vibrant colors

Concrete Materials

Concrete and stone materials are non-metallic with high roughness. They often feature detailed normal maps to show surface imperfections and weathering.

  • Metallic: 0.0
  • Roughness: 0.7-1.0
  • Base Color: Gray to brown tones

Gray Polished Granite

Polished granite combines natural stone patterns with a smooth, reflective surface. It's non-metallic but achieves low roughness through polishing, creating clear reflections.

  • Metallic: 0.0
  • Roughness: 0.1-0.3
  • Base Color: Gray with natural variations
