The DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters. material layer is used for dull, non-reflective materials. See the Diffuse MaterialThe representation of the surface or volume properties of an object. topic in this manual for more information. Figure 1 uses a Layered Material with a SpecularAmount of specular reflection, or the mirror-like reflection of light photons at the same angle. Used for transparent materials such as glass and water. material as the base material and the Material Layer Diffuse node connected to the material layer list.

Diffuse - The layer's diffuse color.
TransmissionA surface characteristic that determines if light may pass through a surface volume. - The layer's transmission color. This can be used for thin translucent objects.
BRDF Model - Determines how light reflects or refracts on the surface.
Roughness - The Diffuse layer's roughness. High values simulate very rough surfaces like sandpaper or clay.
Bump - Simulates a relief, using a Greyscale texture interpreted as a Height map for the layer.
Normal - Distorts layer normals using an RGB image.
Opacity - Controls the layer opacity with a Greyscale texture.
