With this addition, the bottle will look like
Figure 6-27
.
Note the subtle difference in shading in the areas
where the Fresnel reflections come into play.
Depending on the type of material, a clear glaze is sometimes added. Increasing the Clearcoat Amount
value will simulate this effect. Clearcoat adds a small amount of unblurred reflection that increases with the
incidence angle (Fresnel effect). This is illustrated in
Figure 6-28
.
Figure 6-27:
The bottle material with a gradient mapped to Diffuse Amount. Notice the slight darkening
on the surfaces that are at a glancing angle.
