I was reading the tut. on this site about skinning and was uncertain about part of it. It says to original model and skins from the asset.0pk3 file. Lets say I was editing Jedi trainer what files and extensions exactly am I supposed to extract? The tut. says go down the list unitl you find all the files for that model you want to modify but what files are they exactly?

You have to extract the whole character thing like you want to edit Jedi Trainer extract the Trainer_Pats.jpg and Trainer_Torso.jpg etc.
all the jpeg files the skin file the icon file the amni sound thing stuff like that.
Hope that helped
