I’ve set up an actor that contains a few sound sources. On one of these sources, I have enabled the low pass filter and have set up some blueprints to change the filter frequency via a lerp. unfortunately, this does not work.
I have verified that the lerp is indeed spitting out the correct, desired frequency, but it seems that it is not possible at the moment to change the frequency at runtime.
This is clearly a bug (otherwise, why would there be a node!)
One of our coders checked the node itself, and verified that it is actually being called…
Does anybody have any ideas about a solution - or know a possible workaround?
