How it works...
This time we started by mixing a
Glass BSDF
shader and a
Transparent
shader
node, modulated by a
Fresnel
node, and we set the
Index Of Refraction
of both the
Fresnel and the glass to the value of ice. We also added a
Glossy BSDF
shader to
provide specularity, mixed by a
Layer Weight
node set on
Facing
(that is, the more
a mesh normal is facing the point of view, the more evident is the specular effect).
Then, by using mixed procedurals textures we created the bump effect to perturb the
object's surface (and note that the bump is also actually affecting the material's re-
fraction).
