Smoothness
| Minimum Inspector Level | Basic |
| Available since | 1.0 |
This parameter defines how smooth the surface of the material is.
This parameter has also differences based on the inspector mode you selected.
On the basic level you only have a slider to decide whenever a material is smooth or rough.
On this level you have the ability to set both the slider and a smoothness map to map areas of you model to be smooth or rough. If you use a smoothness map, you should keep the slider set to 1.
The smoothness map is not actually used by the shader directly, but it's used to generate it's own MSOT map by sampling the red channel of the smoothness map.
On this level you only have a slider to decide whenever a material is smooth or rough. This is due to the fact that the smoothness map is sampled from the MSOT map and on expert level i assume people can handle making that texture by their own for more flexibility.
