Yeah this is correct, now you just need to activate this mix when you want the audio to be muffled

Right, I'm doing this in my player controller...seems correct?

i dont think the player controller would be the correct place to do this

#

are you aware of break pointing and Print Strings to help debug

Sure, using a print statement I can confirm that it's firing off, but I can also try placing it somewhere besides the player controller to see if that makes a diff

When the sound is playing, open the control bus mix asset and hit the button at the top that says Activate Mix and see if you hear the filter being applied

Thank you for sticking with me through this! With the sound playing, pressing ActivateMix doesn't seem to have any affect

#

Just verifying that this is the correct setup for the Controller Bus?

#

Seems like the only way I can get this to actually do anything at all is when I change the default value on this LPFCutoffFrequency asset by hand (pretty sure that's not the correct way!)

hmm, strange - to test, add the CB to a specific MSS (in the modulation section) you want to filter and see if it works when activated

Steve, thanks for all the help - I did get this working actually late last night, though unfortunately it was one of those things where I changed a bunch of stuff and I'm not really sure which thing actually fixed it. Either way, working now!
