Hi, You don't know about it ? Just put a trigger_once in the same area of your cinematic trigger, or anywhere you want your music to change. In the values your enter "target music1" for exemple. You can also edit a NPC to give him the value "NPC_target music1", so when he will die it will do the target. And you place anywhere (position don't affect anything) a target_play_music, editing it with "targetname music1" and "music music/nameofthemusic.mp3 or wav". NOTE: A wave file always display a yellow line in the corner of the game everytime it loops, so I recommand, if you use wave, to have in your config files "cl_noprint 1" to avoid stupid yellow lines during the game.
