Creating a Realistic Metal Material

../../../_images/material_metal.png

Metal material

Main parameters:

  • Diffuse color almost black (0.01 - 0.05)

  • Reflection color almost white (0.9 - 0.99)

  • Fresnel enabled with strong IOR (10+)

  • OR Fresnel disabled

  • Varying glossiness (0.0 - 0.5)

This setup uses RED::IMaterial::SetupRealisticMaterial to produce metallic surfaces. A metallic surface is seen through its reflections. Chrome metals are almost perfect reflectors, while some other metals may exhibit more or less glossy reflections. Therefore, a metallic setup will mainly rely on its reflection parameter setup: the reflection color, the choice between Fresnel based or plain reflections, and the quantity of glossiness to setup.
