Brlcad/How to mged/command/mater

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.

mater region1.r plastic
 * 1) Set the material properties for region1.r to plastic

Setting the material shader properties
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.
