Composite material composites (page 3–1016) up
to 10 materials. The materials are superimposed
from top to bottom, as listed in the rollout.
Materials are combined using
additive opacity
(page 3–1000)
, subtractive opacity (page 3–1111) ,
or mixed using an Amount value.
Note: If even one sub-material has its shading set to
Wire (see
Shader Basic Parameters Rollout (page
2–1310)
), t he entire material displays and renders
as a wire material.
Inter face
Base Material—Displays the Material/Map Bro wser
(page 2–1256)
, where you assign t he base 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 m aterials are assigned.
Che ck box —When on, uses the material in the
composite. When off, doesn’t use it. D efault=on.
Button—Displays the Material/Map Browser (page
2–1256)
, where you assign a material to composite.
ASM buttons—These buttons control how the
material is composited. Default=A.
A—When on, this material uses additive opacity
(page 3–1000)
.Colorsinthematerialaresummed
based on their op acit y.
S—When on, this material uses subtractive
opacity (page 3–1111)
.Colorsinthematerialare
subtracted based on their opacity.
M—When on, this material mixes materials based
on the Amount. Both color and opacity are
blended as they are when you use a
Blend material
(page 2–1397)
with no mask.
Amount spinner—Controls the amount of mixing.
Default=100.0.
For additive (A) and subtractive (S) compositing,
the Amount can range f rom 0 to 200. When the
Amount is 0, no compositing happens, and the
material below is not v isible. When the Amount is
100, the composite is complete. When the amount
is greater t han 100, compositing 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 below is
not visible. When the amount is 100, compositing
is complete, and only the material below is visible.
