Shading Display

The Shading Display tab lets you customize shading display settings without having to apply extra material. These parameters can be used only if at least one of the shading modes is activated in the View toolbar.

Select the Shading Display tab to access options for:

General parameters

Deactivate ambient lighting
Ambient light illuminates a model from all directions in addition to specific light sources. This option affects the standard model shading as well as the material visualization.

By default, ambient lighting is activated.

Default shading parameters

These options impact shading visualization, but material visualization is not affected by these options.

Ambient & Diffuse coefficient
Ambient light defines the intensity of light diffused in any direction by the object, even if not lit by any light source. Diffuse light defines the intensity of light diffused by the object when lit by light sources. The same coefficient is used to define the ambient intensity and the diffuse intensity; you can enter a coefficient between 0 and 1.

By default, the ambient and diffuse coefficient is set to 1.

Specular coefficient
Defines the intensity and color of light reflected in one particular direction (highlights). Typically, a polished object has a high value for the specular reflectance coefficient, while a matte surface has a lower value. You can enter a specular coefficient between 0 and 1.

By default, the specular coefficient is set to 1.

Roughness coefficient

Defines the dullness of the object; i.e., the size of the reflecting zone. Setting the value to a minimum generates very sharp highlights on very shiny surfaces. Setting the roughness to a higher value generates large specular spots, creating a duller effect on rougher surfaces. You can enter a roughness coefficient between 0 and 1.

By default, the roughness coefficient is set to 0.41.
