So I got the ark dev kit installed, and found the sound in question:
ARK\ShooterGame\Content\PrimalEarth\Sound\SFX\Generic\PW_wep_switch_weapon.uasset
ARK\ShooterGame\Content\PrimalEarth\Sound\SFX\Generic\PW_wep_switch_weapon_Cue.uasset
ARK\ShooterGame\Content\PrimalEarth\Sound\SFX\Generic\Poop.uasset
ARK\ShooterGame\Content\PrimalEarth\Sound\SFX\Generic\Poop_Cue.uasset
These are what I want to mute/remove, but I have no idea how to proceed from here… how can I mute these sounds and turn it into a mod that my friend can load?
