Let's Build the RPG! - 62 – Underground Acoustics and Sound – Audio Volume UE5 Cave Tutorial

In this episode we set up our underground cave environment to accurately reflect sounds whenever the player character is within that environment. This includes stuff like footsteps, gameplay abilities, vocalizations, etc., but also we set up a water drop sound to spawn with reverb every water drop into our cave pool that we started in episode 58. By the end of this episode you will know all the basics of setting up indoor sound.
