Mask Sets a map to use as a mask. The degree of blending between the two materials depends on the intensity of the mask map. Lighter (whiter) areas of the mask show more of Material 1, while darker (blacker) areas of the mask show more of Material 2. Use the check box to turn the mask map on or off. Mix Amount Determines the proportion of the blend (percentage). 0 means only Material 1 is visible on the surface; 100 means only Material 2 is visible. Unavailable if you have assigned a mask map and the mask's check box is on. You can animate this parameter. Create Material Preview on page 5333 is useful for testing the effect. Mixing Curve group The mixing curve affects how gradual or how sharp the transition between the two colors being blended will be. It affects the blend only when a mask map is assigned. TIP For mottled effects, blend two standard materials using a noise map as a mask. Use Curve Determines whether the Mixing Curve affects the mix. This control is available only when a mask is assigned and active. Transition Zone These values adjust the level of the Upper and Lower limits. If the two values are the same, the two materials meet at a definite edge. Wider ranges give more gradual blending from one sub-material to the other. The mixing curve displays the effect of changing these values. Composite Material Material Editor > Type button > Material/Map Browser > Composite Composite material composites on page 7937 up to 10 materials. The materials are superimposed from top to bottom, as listed in the rollout. Materials are combined using additive opacity on page 7901, subtractive opacity on page 8140, or mixed using an Amount value. NOTE If even one sub-material has its shading set to Wire (see Shader Basic Parameters Rollout on page 5397), the entire material displays and renders as a wire material.
