Extended Parameters Rollout (Standard Material) 1471
Self-Illumination ( page 2–1487) makes a
material appear lit from w ithin.
Self-illumination is not available for the Strauss
shader (page 2–1483).
Opacity (page 2–1488) controls how opaque or
transparent a material is.
Diffuse Level (page 2–1489) controls the
brightness of the diffuse color component.
Diffuse Level is available only for the Anisotropic
(page 2–1480), Multi-Layer (page 2–1481),and
Oren-Nayar-Blinn (page 2–1482) shaders.
Roughness (page 2–1490) controls how quickly
the diffuse component blends into the ambient
component.
RoughnessisavailableonlyfortheMulti-Layer
(page 2–1481) and Oren-Nayar-Blinn (page
2–1482) shaders.
Highl ight Controls
The second part of the Basic Parameters rollout
contains controls for specular highlights, which in
some ways are the greatest difference between the
various shaders. S ee these topics for a descr iption:
Anisotropic Highlights (page 2–1480)
Blinn, Oren-Nayar-Blinn, and Phong Highlights
(page 2–1493)
Metal Highlights (page 2–1494)
Multi-Layer Highlights (page 2–1495)
For information on highlights with the Strauss
shader, see Strauss Shader (page 2–1483).
Translu cen cy Con trols
For the Translucent shader (page 2–1484),an
additional group on the Basic Parameters rollout
contains controls for translucenc y (page 2–1491).

Parameters rollout
The Extended Parameters rollout is the same for all
shading types of Standard material. It has controls
related to transparency and reflection, as well as
options for Wire mode.

Refraction for some common physical materials.
These can be used to create Standard materials
with realistic transparency.
Additive Opa cit y a nd the Alpha Channel
By default, additive opacit y does not generate
an alpha value. In other words, the alpha value
is zero, indicating no transparency. This gives
correct results with backgrounds in renderings,
but if you want to composite objects with additive
opacity using video post (page 3–311) or a different
compositing program, you might want to have
additive opacity render with transparency. To do
so, add the following line to the [Renderer] sect ion
of the 3dsmax.ini fi le, and then restar t 3ds Max:
AlphaOutOnAdditive=1
To rever t to the default method of rendering
additive opacity, in the 3dsmax.ini file, change the
val ue of AlphaOutOnAdditive back to 0 (zero),
and then restart 3ds Max.
