§ 16.90.5.40 - roughness (SceneScript element)

 <roughness EXP> 

This language element may be used inside a  <trait>  block.

EXP can vary from 0 upwards. 0 is a very rough surface, and 100 is a comparatively smooth surface. This value is used in controlling how light reflects from a surface, especially as the light reflection approaches a direct (180 degree) reflection. For a highly polished object, use a large value. For a rough object where you want a large degree of diffusion of light, use a small value.
