   Diffuse Node.


The *Diffuse* :abbr:`BSDF (Bidirectional scattering distribution function)`
node is used to add Lambertian and Oren-Nayar diffuse reflection.


Inputs
======

Color
   Color of the surface, or physically speaking,
   the probability that light is reflected or transmitted for each wavelength.
Roughness
   Surface roughness; 0.0 gives standard Lambertian reflection, higher values activate the Oren-Nayar BSDF.
Normal
   Normal used for shading; if nothing is connected the default shading normal is used.


Properties
==========

This node has no properties.


Outputs
=======

BSDF
   Standard shader output.
