Default Nodes
Material Output Node
● The Material Output node is used to output surface material information to a surface object.
● Inputs
- Surface. The surface output of the material.
- Volume. Used to output of the different volume shaders.
Diffuse BSDF
● The Diffuse BSDF 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.
