Hey
In my mod, there is an npc that plays faceposer scenes that you can hear everywhere around the map similar to how you can hear Glados voice in portal.
I did it by using a sound script file and changing the "soundlevel" from "SNDLVL_NORM" to "SNDLVL_NONE" (from what I saw this is what they did in Portal's sound scripts).
Anyway, in game it sounds great, and I can hear my npc talking no matter how far I am from him, but my problem is that I'm using closed captions, and they are showing only when I'm getting close to my npc, once I go far I can still hear him without problems, but the closed captions stop showing.
Anyway to get this working? in Portal of course there isn't such a problem.
