Ok, got everything working fine so I attempted a skin. Started with the Imperial Saboteur and went for a 1930's steampunk style hero type guy. It's mainly an edit of the already existing skin, but I wanted to start simple.
The skin worked perfect, first time, except for the sounds.
I looked at model someone had made and mimicked the folder structure and made sure the sound files were named identically. There was no sound.cfg file in that model's pk3, so I deleted the .cfg from mine...but when I started up the game...it was stil using the saboteur's sounds.
How do I set up a skin to use custom sounds?
