Blind Forest UE5 Audio Based Game

To create this peculiar Audio-Noise response, I created a completely dark material, and applied it to infinite extents in the world, using a post-process volume.

Then within a certain amount of time, an instance of a dynamic colour material is spawned (with the stencil settings enabled on the engine), that is expanded on circular shapes using a defined timeline rate, that when it ends destroys itself, and followed by a report noise function every time an audio file is played, so the AI of enemies are aware of it.

There are 5 different colors for noises:

Green: stealth mode/ friendly objectives.

White: footsteps of the player.

Red: Enemies.

Yellow: distracting noises for enemies.

Blue: player's voice inside the game.

To create the guiding wind system:

For the audio loop used on the wind trail that can we hear,I used a pink noise generator using Metasounds, that spawns on the back of the player and moves towards the direction of your current objective, with a small and focused spheric occlusion and long fall-off distance, to be able to locate the source.

Then I spawned a leave particle system in front of the player, and a force aiming at the current objective of the player, visually complementing the mechanic.

Everything combined gives the player a sense of where to go in this dark environment.

To enable the voice of the player inside the game, I used an audio capture component on the player blueprint, that spawns an instance of this dynamic material every time it reaches a volume threshold, followed by a report noise for the AI.
