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. layer creates dull, non-reflective MaterialsA set of attributes or parameters that describe surface characteristics.. See the Diffuse MaterialThe representation of the surface or volume properties of an object. topic in this manual for more information.
Figure 1: Diffuse Layer parameters
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. See the BRDF Models topic in this manual for more information.
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.
Layer Opacity - Controls the layer opacity with a Greyscale texture.
