Angular Blend and ClearFinish Procedural Materials
AccuRender 3.1 includes two new procedural materials: angular blend
and ClearFinish. Both procedures blend between two different
materials to create special effects. Use angular blend to create
materials that change characteristics based on the angle of view to
the surface of the object. Use ClearFinish to emulate thin, clear
finishes on the surface, like car paint and lacquer finishes.
Angular Blend
In the following angular blend example, the material changes color
from a light blue to purple. The surface areas that face the viewer
are light blue. As the surface starts to curve away from the view,
the color blends into purple.

To create an angular blend procedure, specify two materials and start
and stop angles.

If the angle of the surface is 0 degrees from the view and the start
angle, the first material will show completely. In the area of the
surface that is angled between the start angle and the stop angle,
there will be a blend of color from the first material to the second
material. From the stop angle to 90 degrees from the view, the second
material will be the only material showing.

ClearFinish Material
Like angular blend, ClearFinish manages two different materials based
on the materials angle to the view. ClearFinish emulates
finishes that are covered with a transparent layer. These materials
tend to be a deep color when you look directly at the surface, but as
the surface curves away from the view they become highly reflective.
Car paints with a clearcoat or clear lacquer finishes are good examples.

To create a ClearFinish procedure, specify a base color and a top coat.

The base material is the main color of the object. Use the color
selector to choose the main color of the material.
The top coat is a transparent material that lies on top of the base
material. You can adjust the index of refraction (IOR) to control how
reflective the top coat is. The higher the IOR, the more reflective
the top coat. You can also tint the top coat with a color. This way
you can get the material to change the base color as it moves into it
reflective state. |
