This is for mixing two textures together according to a cosine wave. In the example below, a Checks Mix was combined with a GaussianSpectrum using a Cosine Mix Texture and connected to 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. channel of a Diffuse materialUsed for dull, non-reflecting materials or mesh emitters..
