This command will ghost a matrix. Ghosted matrices will appear transparent when rendered, creating effects such as a see-through surfaces. A ghosted matrix automatically switches to a higher level of priority when rendered in order to ensure objects above and below the matrix are visible. The Ghost Mode with a range of 0 to 5 specify the type of ghosting to perform. Be aware that ghosted matrices cannot be seen in a reflection created by the SET REFLECTION SHADING ON command.
