Different materials have different finishes. Surface finishes include Dull, Low Gloss, Semi Gloss, High Gloss, Liquid, Fully Reflective, Partially Reflective, Shiny, Fully Transparent, and Partially Transparent. The finish determines how much a material reflects, emits and absorbs light. These factors can affect the lighting in a rendered scene.
To edit the surface properties of an element’s materials:
Select the element in your drawing.
Right-click and select Properties, or select Edit > Modify Elements > Properties.
In the properties dialog, select the Appearance tab.
On the Appearance page, click the Select button, or click the Texture swatch to access the Materials dialog.
In the Materials dialog, click the Rendered swatch to bring up the Edit Materials dialog.
To change the surface finish of the material (dull, shiny, etc.), make a selection from the drop box in the Surface Properties area. If you want to specify a custom surface finish, select Custom in the list, then click the Advanced button.
If creating a custom finish, specify its properties. These are described below.
Specular. Reflection that creates highlights on materials, making them appear shiny.
Emissive. The amount of light given off by a material. The more emissive a material is, the more self-luminous it appears.
Transparency. The degree to which a material is pervious to light.
Color Bleed. The degree to which different colors blend where they meet.
