🔊Audio/Sound Volume adjustments

To adjust a specific audio volume in-game you need a Slider widget in your settings menu.

You can adjust it directly in the details tab if you have selected a slider in your settings menu widget:

Here in the Use As Sound Volume Slider section make sure to set set Enabled = true. For the Sound Mix Modifier you can just use SCM_NiceSoundMix or feel free to use your own one if you have such a class already. The Sound class is basically for the volume type (so for example a sound class for all your music sound files or another sound class for your sound effects). By default there are 3 Sound classes that you can use:

• SC_Music

• SC_SoundFX

• SC_UserInterface

However, you can add more sound classes.

Now to actually influence your audio volumes when adjusting these sliders you need to open your Sound Files or Sound Cues and just set the corresponding Sound Class in there. Here is an example for for the UI click sound effect:

Regarding sounds that are a bit longer as your game's music you might need to do another adjustment. Because when turning the sound volume to 0 a sound will no longer be played. This means by default that a sound that was playing and then turned to volume of 0 and then increased the volume again would restart, so it starts playing from the beginning. This is probably no problem for short sound effects but for music this behviour does not feel good. To fix this you need to open the Sound Wave Sound Cue or again and set the Virtualization Mode to: Play when Silent.

Master Volume Sliders

Another feature is the Overall volume or you can call it also Master volume. This is not affecting directly the the volumes of sound classes. Instead it's influencing other volumes sliders. It's basically a multiplier for the volume of other sliders. If you select it in your widget you need to tick Is Master Volume in the details tab:

The Master Volume ID is connecting other non-master volume sliders with this master slider. So if a Master Volume Slider is set to the Master Volume ID 0 it influences the volume of all other volume sliders that are set to the Master Volume ID 0. If you want to go advanced with the volume adjustments in your game you can add different master volume sliders with other Master Volume ID's which then can incfluence other, related Volume Sliders.
