Composite Material

Base Material—Displays the Material/Map Browser, where you assign the 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 materials are assigned.

Check box—When on, uses the material in the composite. When off, doesn't use it. Default=on.

Button—Displays the Material/Map Browser, 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. Colors in the material are summed based on their opacity.

S—When on, this material uses subtractive opacity. Colors in the material are 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 with no mask.

Amount spinner—Controls the amount of mixing. Default=100.0.

For additive (A) and subtractive (S) compositing, the Amount can range from 0 to 200. When the Amount is 0, no compositing happens, and the material below is not visible. When the Amount is 100, the composite is complete. When the amount is greater than 100, compositing is "overloaded": transparent portions of the material become more opaque, until the material below is no longer visible.

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.
