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 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: 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.
