# Physical Material

Physically based rendering (PBR) materials use a physically correct shading

## Description

Physically based rendering (PBR) materials use a physically correct shading to create a material that will react 'correctly' under all lighting scenarios

**M** | **Model Element** (*T+ Model*) | A Three Plus Model, Mesh, or Brep

**C** | **Color** (*Colour*) | The material color

**X** | **Roughness** (*Number*) | How rough the material appears. (0.0 smooth mirror to 1.0 fully diffuse.)

**R** | **Reflectivity** (*Number*) | Degree of reflectivity, from 0.0 to 1.0.

**M** | **Metalness** (*Number*) | How much the material is like a metal. Non-metallic materials such as wood or stone use 0.0, metallic use 1.0, with nothing (usually) in between.

**S** | **Sheen** (*Number*) | The intensity of the sheen layer, from 0.0 to 1.0.

**Sc** | **Sheen Color** (*Colour*) | The color of the sheen layer

**L** | **Clearcoat** (*Number*) | Represents the intensity of the clear coat layer, from 0.0 to 1.0.
