Custom collision sound for grenade

[Draks66]

Hello there.

I made grenade launcher weapon, like in old games like Quake 1 or Quake 2. It fires grenade projectiles which explodes after several seconds. I want to make my own sounds for projectile impact. I tried by using ImpactData but it works only once when projectile hits wall after the shot, after that it returns to standard sounds. Is there any way to make sound working every time when projectile collides with surfaces?
