of one another using the
alpha channel (page

that already contain an alpha channel.
The controls for a Composite map are essentially a
list of the maps it combines.
Viewports can display the multiple maps in a
composite map. For multiple map display , the
display driver must be
OpenGL (page 3–884)
or
Direct3D (page 3–888)
.The
software display
driver (page 3–884)
does not support multiple
map display.
