Maps for you

[Kaplan]

I follow owsupport instructions but when i load the ground bitmap on grndsec, i don't have GBI menu and the "autopack" option.

Tutorial is maybe for older version of grndsec, but steps should be very similar. Just load your BMP to grndsec (if you have water in your map, load water image too), click next and choose directory for GBI file.
