Adjust your own footstep volume and perceived footstep volume of the AI enemies.
Lightweight mod that lets you modify certain footstep audio settings for the character controller and the AI enemies.
Originally created this mod to satisfy my own immersion.
I always struggled with the fact that the footstep volume is always the same regardless if I sprinted or crouched
whereas the AI is moving like they're incredibly gracile assassins.
Note: Adjusting your own footstep volume does NOT affect how loud the AI will hear your footsteps.
Features
Individual controllable footstep volume reduction for crouch, walk and run state.
Increases the unit size of the AI's footstep audio node by X, basically lets you hear AI footstep over a larger distance so it's harder for them to sneak up on you
(Be aware that if this value is too high it could impact the perceived audible distance of the AI, so I recommend not setting it higher than 5 or the enemy might appear a lot closer than they actually are)
