Project Acoustics Issues in Unreal 5.1.1

Mike Thal · Sep 23, 2023

Hi Microsoft,

I saw your Project Acoustics presentation in this incredible video. My team and I were so inspired, that we decided to integrate it into our game. Would you be able help with some issues that we're running into or direct us towards someone who can?

After following the directions in the video above, I'm having trouble getting the acoustic voxels and probes to show up in our level and the default Third Person Example Map. I'm able to bake acoustics, but it's not making a noticeable difference to the sound. Because of these two details, I'm worried that the plugin isn't working as intended.

Here's some extra context that may help!

Using UE 5.1.1 (not using Wwise)

Geometry and Navigation are both tagging more than 0 items.

The maps have NavMeshes

Thanks again and I hope you have a great day!

Cheers,

Mike

This is a consumer tech support forum, no one here is equipped to answer those questions.

I suggest you contact your id@xbox handler and ask them how to proceed

Hi there.

Thank you for reaching out to the forum. "Project Acoustics is a wave acoustics engine for 3D interactive experiences. It models wave effects like occlusion, obstruction, portaling and reverberation effects in complex scenes without requiring manual zone
markup or CPU intensive ray tracing. It also includes game engine and audio middleware integration. Project Acoustics' philosophy is similar to static lighting: bake detailed physics offline to provide a physical baseline, and use a lightweight runtime with
expressive design controls to meet your artistic goals for the acoustics of your virtual world. Ray-based acoustics methods can check for occlusion using a single source-to-listener ray cast, or drive reverb by estimating local scene volume with a few rays.
But these techniques can be unreliable because a pebble occludes as much as a boulder. Rays don't account for the way sound bends around objects, a phenomenon known as diffraction. Project Acoustics' simulation captures these effects using a wave-based simulation.
The acoustics are more predictable, accurate and seamless. Project Acoustics' key innovation is to couple real sound wave-based acoustic simulation with traditional sound design concepts. It translates simulation results into traditional audio DSP parameters
for occlusion, portaling, and reverb. The designer uses controls over this translation process."

Only in the minds eye.

Here's mine

Pics a bit small but there is a Sharp Aquos 60" TV, Sony STRDN1000 7.1 AV Receiver, Boston Acoustics Soundware XS 5.1 speaker system, Eltax Concept Floorstanders and Eltax Monitor III Bookshelf speakers. Sky Box, additional Blu Ray player (now been replaced
with a Wii) and my PC is there now also (I won't go into the specs but it's pretty powerful).

[/quote]Wow Unreal. That's just... unreal.

i am not saying to just simply port our games from project spark, i mean that to remake the games from project spark to a auctuall game engine, as in redo what you just make in project spark, only do it again in a game engine. to see my point, someone remade tomb raider II in unreal engine.
