What are the neccasery programs to turn a multiplayer skin into a single player skin? I already kno that I need to ask for permission from the creator. Thanks for any help.
I don't know of any programs, but try this:
When in singleplayer, press Shift+~ and a console menu will be pulled down. Here type "playermodel" and then the model you want. Say you want to be a stormtrooper, then you type "playermodel stormtrooper". Most skins are based on their names, such as cultist, reborn, swamptrooper, etc. For an entire list of such names, check out our search and type in "npc" in the Jedi Academy forum. You'll get a few results with the list or otherwise Google can help.
For those that you have downloaded from the net, however, I have no idea. I tried it, but it just says that the model was not found.
Beware however, that if you turn to someone who is actually your enemy, like Boba Fett or a stormtrooper or something, you will not be able to hurt your enemies. I recommend to turn to Kyle for some nostalgia ;)
