Put one of the following in your commandline/ini file
Output_Alpha=bool ;Sets alpha output on/off
+UA ;Sets alpha output on
-UA ;Sets alpha output off
Note that to output the alpha channel you must be using either .tga or .png
output
Read the docs for "File Output Options" and "Image maps" - down the bottom under
"Using the Alpha Channel"

You may or may not be able to use these formats & might want to export the alpha
channel as a greyscale image & remove it.

Hope this was of some help.
