******** Settings ******** .. admonition:: Reference :class: refbox :Panel: :menuselection:`Material --> Settings` Renderer Settings ================= While shading nodes control the appearance, these settings control the quality and algorithms that each renderer uses to render the material. - :doc:`Eevee specific settings ` - :doc:`Cycles specific settings ` Pass Index ========== Pass Index Index number for the *Material Index* :doc:`render pass `. This can be used to give a mask to a material and then be read with the :doc:`ID Mask Node ` in the compositor. Viewport Display ================ These settings control the 3D Viewport display in solid shading. They provide a faster alternative to full shader nodes, which may be too heavy or distracting for tasks like modeling, layout or sculpting. Color Diffuse or metal surface color. Metallic Blends between a non-metallic and metallic material model. A value of 1.0 gives a fully specular reflection tinted with the base color, without diffuse reflection or transmission. At 0.0 the material consists of a diffuse or transmissive base layer, with a specular reflection layer on top. Roughness Specifies microfacet roughness of the surface for metal and specular reflection.
