With the Ansirals new tool you don't have to edit any mission files or RoF campaign files.
Just add the nam of your squadron mates name in ACES.ini with a corresponding skins and it'll appear in the mission.
Works best with "mods on" of course, more skins to choose from
For example if you have a pilot in your campaign roster called Oscar Richter and you are in J5 DVA's
Just add to Aces.ini
[AlbatrosD5]
Oscar Richter = AD5_generic.dds (made up skin name, just put in here what skin you want)
You can also add your own pilot name in there and it'll work

Handy little tool. Ansiral has added much value to Pat's campaign in the past and looks like he's done it again
