Hi

To run acoustics you need a native harmonic acoustic system (see image below) not a harm. response + act acoustic extension (you should not use this extension use the native system).

See here for a tutorial on how to run harmonic acoustics:

Hi

Yes we will try and remove that video as it is very old (R15) and we are not using the act extension anymore.

To run acoustics say in 2023 R1 you are using, you need the native harmonic acoustic system (see image below).
