The game, apparently, did not provide sounds of water splash after the explosion, in the data I found two similar (non-used in any) sounds for make this feature
- a3\sounds_f\vehicles\crashes\watersplash_1.wss
- a3\sounds_f\vehicles\crashes\watersplash_2.wss
look at YT video before\after
look at config actions to make this work:
- pastebin CfgSoundShaders
- pastebin CfgSoundSets ← just add new class
