Creating a realistic marble material

Marble material

Main parameters:

This setup uses RED::IMaterial::SetupRealisticMaterial to produce a marble. The marble has a diffuse texture that contains the color of its veins. Then, as a marble is generally a well polished surface, we won't setup any surface modification map (no displacement, no bump). Reflections are quite strong over a marble surface, so we set the reflection color quite high. Then, we can adjust the reflectance by controlling the IOR. Increasing the IOR value will strengthen reflections.
