Step #2 is to set proper transparency for the BMP palette.
For that, you can use WE/PES Graphics Studio v04.04.24 by obocaman.
In the right section ("Bitmap Info"), open your BMP, then set all the
colors to be opaque. After that, in palette, select the color(s) that
you need to be transparent (usually some bright green or pink), and
set its opacity to 0%. Save the kit, by right-clicking on it, and
choosing "Save As" menu item.
