The Blend material lets you mix two materials on a single side of the surface. Blend has an animatable Mix Amount parameter that lets you draw material morphing function curves to control the way that the two materials are blended over time.
Blend material combines bricks and stucco.
To create a Blend material, do one of the following:
3ds Max opens a Replace Map dialog. This dialog asks whether you want to discard the original material in the sample slot, or retain it as a sub-material.
The controls for Blend materials are similar to the controls for Mix maps.
To specify a component material, do one of the following:
The parameters for the sub-material are displayed. By default, a sub-material is a Standard material with Blinn shading.
To control the mix amount:
You can also control the mix amount by using a map.
Map used to reveal brick beneath stucco
To control the mix amount using a map, do one of the following:
3ds Max opens the Browser so you can select a map type.
The intensity of pixels in this mixing map controls the mix. When the intensity is close to zero, one of the component colors or maps is visible; when it is close to full intensity, the other component is visible.
The Mix Amount setting is unavailable when a map is assigned to the Mask parameter. If Use Curve is off, the mixing map is used as is. When Use Curve is on, you can use the mixing curve to shift the effect of the mask map's gradient ramp to reveal more of one material and less of the other.
If one material has Show Map in Viewport on, this takes precedence over the Interactive setting. Only one map at a time can be displayed in viewports.
You can animate this parameter. Create Material Preview is useful for testing the effect.
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.
