Note:
If even one sub-material has its shading set
to Wire (see Shader Basic Parameters Rollout (page
2–1466)), t he entire material displays and renders
as a wire material.

By default, the base material is a Standard
material. The other materials are composited by
superimposing them on top of this material, in
order from top to bottom.
Mat 1 through Mat 9—Each of these nine groups
contains controls for a material to composite. By
default, no materials are assig ned.
Che ck boxWhen on, uses the material in the
composite. When off, doesn’t use it. Default=on .
B utton—Displays the Material/Map Browser (page
2–1412), where you assi gn a material to composite.
ASM buttons—These buttons cont rol how the
material is composited. Default=A.
A—When on, this material uses additive opacity
(page 3–906). Colors in the material are summed
based on their opacit y.
S—When on, this material uses subtractive
opacity (page 3–1017). Colors in the material are
subtracted based on their opacity.
M—When on, this material mixes materials based
on the A mount. Both color and opacity are
blended as they are when you use a Blend material
(page 2–1588) with no mask.
Amount spinner—Controls the amount of mixing.
Default=100.0.
For additive (A) and subtractive (S) compositing,
the Amount can range from 0 to 200. When the
Amount is 0, no compositing happens, and the
material below is not visible. When the Amount is
100, the composite is complete. When the amount
is greater than 100, comp osit ing is " overloaded":
transparent portions of the material become more
opaque, until the material below is no longer
vi sible.
For mix (M) compositing, the Amount can
range from 0 to 100. When the Amount is 0, no
compositing happens, and the material b elow is
not visible. When the amount is 100, compositing
is complete, and only the material below is visible.
