I was playing through Black Mesa with the Hardcore V2 workshop addon enabled, and at a point my game crashed. When I opened it back up, my muzzle flashes glitched and now take up the entire screen, making it impossible to see anything I’m shooting at. It does not go away if I restart the game. I attached a couple screenshots of the flash. Any suggestions on how to fix it?
uninstall the mod and verify the game cache
That worked! Thanks!
