So I'm trying to add some guns that were in the game files but not in the game (like the Point Lookout shotgun). But when I use the reload animation used in Point Lookout it doesn't have a reloading sound (Reload G). There doesn't seem to be a way to select the sound in the art and sound tab so I'm assuming the sound is linked to the animation? How can I add a sound (for example the caravan shotgun reloading sound)?
It does have a reload sound in 3rd person, just not 1st.
It's got the editor ID of a sound put in as a text key in the .kf file. Open the 1st person reload anim in NifSkope, click on the controller, look for the Text Keys link and follow it. Then you can edit them.
