I took the ROTJ Luke skin and tried to convert it to SP. How ever every thing I have tried ...nothing...zip...can some one please help me??
I just wrote up the tutorial for this now, so here it is for you, I'm actually wondering if its big enough to warrant calling a tutorial at jk2files.com, heh.
Ok, this is really quite simple, extract the pk3 file you want to lose (eg vader.pk3). Go into the models/players folder, and rename the playername folder to kyle (eg, rename the folder called vader to Kyle) and re-zip the pk3, and name it something different (eg sp_vader.pk3). put it in your gamedata/base folder, and thats it, Vader in single player. Unfortunatley he still has Kyle's sounds, but, later on I'll work on something to change that maybe to, or at least some of them. (will just be another simple tutorial like this). Have fun!
Hope it works for you, its all I did, and I got the fun of playing as Lord Vader himself!
