Occlusion with FMOD Studio

[Simy_Sams]

Hi Sunny,

Thanks for your question.

Your code snippet looks to be okay, but there is something else to take into consideration.

GetChannelGroup does not work until the event has fully been created. To ensure this is the case, please use flushCommands after the code to create the event instance - https://www.fmod.org/documentation/#content/generated/FMOD_Studio_System_FlushCommands.html

Let me know if this has helped.

Thanks,
Richard

Hi Richard,

Thanks for the tip, I tried it and it did allow for a valid ChannelGroup(although pausing the thread like that is not ideal).

Unfortunately, while it “works” and the sound volume is lowered by the occlusion, it doesn’t sound particularly realistic.

It looks like the 2nd parameter to set3DOcclusion, reverb occlusion, is ignored– so in practice all the occlusion is doing is lowering the volume…

i.e. if I call set3DOcclusio(1.f, 0.f), the sound is completely muted.

I see that passing FMOD_INIT_CHANNEL_LOWPASS to fmod init is supposed to turn on some reverb, but it doesn’t appear to do anything for me.

I guess Studio just doesn’t work with occlusion– is there a pluggin that handles this or something?
