Procedural River Sound is actor Blueprint you place in the level. It has spline mesh component which you setup along your river. River Sound Audio Component is spawned and it follows your character along setup spline.

There is 5 different types of water sounds:

• small stream
• big stream
• small river
• big river
• waterfall

I am using this asset in my first Indie Game: Wildlife Rescue Simulator is up on Steam. Please add it to your Wishlist: https://store.steampowered.com/app/2797390

You setup river type by changing values on spline points. Thickness of river mesh indicates which river sound is playing. You can setup different values on each spline point, system will blend different river sounds while your character is moving along the spline.

There is 5 river types and every type has 3 different sounds for close middle and far, they are connected in one Sound Cue with Crossfade by distance node which mean you hear different sounds of the river depending on your distance from it. Each sound is about 20 second loop.

River bluprint actor is fully commented and every public variable is described.

There is detail tutorial how setup River sound step by step.
