Mask center (Sound shader keyword)

The information on this page is specific to Doom 3 and Quake 4.

Description

The mask_center keywork only allows sound from the shader to be outbut through the center surround sound speaker in a 5.1 setup.

Usage

mask_center

Example

ship_engine_rumble
{
    mindistance 100
    maxdistance 1000
    volume 10
    looping
    mask_center
    shakes .1
    sound/last_stand/loop_rumble_center_b.wav
}

Notes

When this is in use, sound only comes from that channel when 5.1 surround is used. If you use 2 channel (stereo) sound the channel will be muted and this sound will not be played.

Note: Quake 4 only:

Quake 4 uses center to do the same thing.
