Create a folder in your FS2 directory, name it MYMOD, inside that create a folder named
data, inside that folders named
models,
maps.
Place the pof file (s) in models, the textures in maps ( should the models have table files, create a folder named
tables and place 'em there, but make sure they have the
.tbm file ending.
Then rightclick on the FRED short cut on your desktop ( assuming you have one on your desktop ),
click properties then add this - Mod MYMOD, apply and voila.
Play around with FRED and to play the newly created mission with new ships:
Fire up the launcher, go to the mod tab and click
select mod, select MYMOD, click apply and have fun!
EDIT: FUBAR was faster.
