The Mix textures mix two TexturesTextures are used to add details to a surface. Textures can be procedural or imported raster files. together, either linearly or according to a cosine wave. In the example below, a Checks mix combines with a Gaussian Spectrum using a Cosine Mix texture, and connects to a 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's Diffuse channel.
