Unity crash when entering playmode with any audio source that has real time reverb enabled.

[antondoggo]

Unity is crahsing when i enter play mode if there is an audio source with real time reverb enabled. My scene mode is set to Unity, I am using Unity 2020.3.27f1, FMOD 2.02.04 and steam audio 4.0.3. I can find another post where it is mentioned to be fixed. Any ideas what could be the issue ? I have followed every step in the manual.

It's crashing randomly for me, i'm trying to make a door soo i'm tweeking thinks, when i change something and enter playmode it crashes 10% of the time. i had success with static objects but when i tryed to make a door with dynamic object it makes the door occlude more of the sound then the rest of the walls, its so weird. i need this pluggin for my horror game, the player should be able to tell where the sound comes from. it looks like a dont understand the export proccess yet, cuz it seams odd to me that u need to export the static objects first then export the dynamic ones, is that right? please help, sorry for my bad english

i had unity crashes with reverb when the game object's audio geometry wasn't properly tagged, the scene geometry not properly exported or the scene geometry asset assigned to the same asset as the audio probes. it's worth checking those aspects even if you use realtime reverb. alternatively try the baked reverb. i'd also recommend looking at the steam audio documentation for unity in tandem with the one for fmod.

@antondoggo @MarceloThunder Can you provide a crash dump or minimal test scene/project? That will help us reproduce the issue faster. Thanks!

@antondoggo Also, the Unity ray tracer is not intended to be used for real-time reverb simulation, since it's not performant enough. Do the Default or Embree ray tracers not work for you? If so, is it due to crashes/bugs, or is there some missing functionality you need for your project?

@MarceloThunder Can you provide more details on the materials you've configured for the walls as well as the door?

We've just released Steam Audio 4.1.0, which includes various crash fixes: https://github.com/ValveSoftware/steam-audio/releases/tag/v4.1.0.

Try it out and let us know if these crashes persist in the new version.
