The Composite material mixes several materials using masks (figure 1). This is much cleaner than using several chained Mix materials. If a mask is not connected, the material's Opacity is used. The first MaterialThe representation of the surface or volume properties of an object. pin becomes the base layer.

Used for dull, non-reflecting materials or mesh emitters. and Glossy materialUsed for shiny materials such as plastics or metals. are blended using the Composite material with a Marble Texture as a mask.


Composite Material Parameters


DisplacementThe process of utilizing a 2D texture map to generate 3D surface relief. As opposed to bump and normal mapping, Displacement mapping does not only provide the illusion of depth but it effectively displaces the actual geometric position of points over the textured surface.

Material Mask

Controls the Material’s opacity using an Input map. If a mask is not connected, the Material's opacity is used.
