Note:
When the IOR equals 1.0, there is no
refraction, and calculating the transparency can
take less time than when the material is refractive.

or shader to one of the basic parameters of the
DGS material. This is comparable to mapping
a component of a standard material; by adding
shaders, you can create a shader tree that generates
complex effects.
Click the button for a com ponent to display the
Material/Map Browser (page 2–1256) and assign
the map or shader. Use the toggle at the left to turn
the effect of the map off or on.
The button to the right of each main shader
button is for shaders that can return multiple
parameters. If a shader that retur ns multiple
parameters is assigned to the component, the
button’s tooltip shows the p arameter name.
Clicking the button displays a

are the only shaders with
multiple return values provided with 3ds Max. You might
encounter multiple return values in shaders provided
with other shader libraries or custom shader code.
For all the DGS material components, the available
mental ray shaders are the same:
