This is a child page. You can use Parent in the quick nav bar at the top or the bottom of the page to navigate directly back to the parent of this page. Some child pages are more than one level deep, and in that case will require more than one Parent click to reach the outermost document level. - 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.
