Menu Blending attributes

Blending section
Sets the overall opacity of the material layer. A value of 0 shows the base material, a value of 1 the layered material.
Defines the way how the blending is calculated
This mode determines the opacity of the layer directly, without any dependency on the incident angle.
Curve: The weight is multiplied by a Fresnel-like customizable curve. This method is intended to provide artistic control.
The weight is multiplied by a Fresnel curve, calculated using the provided index of refraction. This is typically the physically-correct approach to rendering varnishes, clear coats, and Fresnel reflections.
Fresnel (Advanced): Same behaviour as Fresnel.
Refraction Index
Defines the refraction taken into account by the Fresnel term to define the specular reflection.
