can anyone tell me how i change the taunt on any skin?
try this First, you need to convert it to a .mp3
The easiest way to build a .pk3 structure, in my opinion, is to use this Bot Editor tool. I can't find a download link right now, but I originally got it from JKII.net. You can ask it to set up all your directory structures for the model as well as custom sounds.
Basically what you need is a sounds.cfg in your skin folder (Models/players/Skinname) that contains the following:
where SkinName is whatever your skin is named, and m is male. For female, of course, just put f. This is basically to tell it that if it doesn't find the other sounds, which MP Default sounds to use, Male or Female.
In your pk3 file, you'll have the following folders: models/players/SkinName sounds/chars/SkinName/Misc
In the Misc folder, you would put the taunt.mp3 (and any other custom sounds you want to include.
Hope this helps clear it up. If not, a better way to figure it all out might be to download a skin that includes a custom taunt and look at the way it was built.
