DEPRECATED. This shader is unsupported, but it may still get installed with Softimage to provide compatibility with older scenes that
use it. It is recommended that you replace unsupported shaders in your scenes with equivalent shaders from the current Softimage
shader library.
Material (Soft3D)
Output: Color (RGB) value
Simulates a film of dirt and dust.
Uses all of the parameters for the default Softimage material settings. It produces the dust effect on top of the surface
to which it is attached and respects the underlying material and textures.
Dust is deposited, depending on the surface angle in global coordinates, with positive Y being up. A horizontal surface gets
the most dust, tapering off to no dust for a vertical surface and no dust for inverted surfaces. Dust color fades into the
surface color: the specular is reduced toward black (to get rid of highlights), and the transparency and reflectivity are
attenuated appropriately.

The shader's name. Enter any name you like, or leave the default.
|
|
|
Selects the color of the dust that accumulates on the surface.
|
|
|
Determines how strong the dust is attracted to the surface. The dust sticks completely to flat surfaces and not at all to
perfectly vertical surfaces. Stickiness controls how much dust sticks to surfaces between those two extremes. The default
is 0.7.
|
|
|
Controls the overall thickness of the dust. The default is 1.
|
Noise
|
|
Turns on noise in the dust, which adds randomness and texture. The default is on (otherwise, the dust looks more like paint).
|
|
|
Controls the overall intensity of the noise. A value of 0 results in no noise; a value of 1 results in full-strength noise.
The default is 0.7.
|
|
|
Defines the overall scaling of the noise in the dust. Increasing this value makes the features smaller. The default is 10.
|
|
|
Controls how much detail is in the dust. Higher values make it finely detailed; lower values make it more gradual. The default
is 3.
