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.
Shader Type: Material (Soft3D)
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.
