Setting up an occlusion area inside a Audio Area Entity

Hi Everyone,

I am looking to set up an occlusion area with a low pass filter within ambience area.

I have the following set up:
Audio_Occlusion_1.png (798.1 KiB) Viewed 7003 times
I have 2 Rtpc variables for the sound:
Amb_Fade (0-1) (standard fade in) for the larger blue area
Occulision (0-1) (low pass filter) for the smaller red area

With the larger volume (blue) I want to have set the Amb_Fade Rtpc (works fine as per tutorials)
With the smaller volume (red) I want to set the Occulsion Rtpc.

Following the examples - setting up the fade in Rtpc was straight forward. However, when I try to link the 2nd red area to the same AAE to adjust the Occlusion Rtpc it does not seem to work.

How do you adjust 2 Rptc parameters with different AudioAreaEntity Regions with the same ambient sound? Or is this not possible and do I need to do it a different way.

Hi Denis,
Is this with a custom project or GameSDK?
Also which engine build are you running?

I have two pictures here of the setup you peobably are looking for.
This is the area setup I propose. Each area has its own AAE setup.

And the corresponding FG setup. Note that the second RTPC Node is assigned to the first AAE to drive the occlusion there.
