I can't solve this. I have a bunch of custom sounds that I put in a hakpack. They show up when I'm editing sound objects, and they play fine in the editor and in game.
Then I try using these custom sounds through the PlaySound script (I've used AssignCommand and ExecuteScript on the PC to play it on), and no matter how I set it up, custom sounds will not work.
I changed the script to run a sound that comes with the game, and it does work.
Does PlaySound just not play sounds from hakpacks?
