The mater command is used to set the material properties for a previously defined region. This includes parameters, such as the material shader, the shader properties, the rgb colour values and any inheritance properties of the materials.

# Set the material properties for region1.r to plastic
mater region1.r plastic

Setting the material shader properties[edit]

The shader properties that can be configured depends on the type of material shader being utilized. The following example shows how to set the transparency, reflectiveness, and shininess properties for a plastic material.

mater region1.r plastic "plastic tr=0.3 di=1.0 re=0.2" 255 0 0 0

Note that the shader and shader properties are passed as a single parameter enclosed in quotation marks. The quotation marks are necessary for grouping parameters separated by spaces.
