Inspector
Material Merge controls
Controls Tab
The Controls tab includes a single slider for blending the two materials together.
Blend
The Blend behavior of the Material Merge is similar to the Dissolve (DX) node for images. The two
materials/textures are mixed using the value of the slider to determine the percentage each input
contributes. While the background and foreground inputs can be a 2D image instead of a material, the
output of this node is always a material.
Unlike the 2D Dissolve node, both foreground and background inputs are required.
Material ID
This slider sets the numeric identifier assigned to the resulting material. This value is rendered into the
MatID auxiliary channel if the corresponding option is enabled in the renderer.
Common Controls
Settings Tab
The Settings tab in the Inspector is duplicated in other 3D nodes. These common controls are
described in detail at the end of this chapter in “The Common Controls” section.
Phong [3PH]
The Phong node
Phong Node Introduction
The Phong node is a basic illumination material that can be applied to geometry in the 3D scene. It
describes how the object responds to light and provides multiple texture map inputs to allow fine
control over the diffuse, specular, and bump map components of the material.
While producing a highlight similar to that produced by the Blinn model, it is more commonly used for
shiny/polished plastic surfaces.
