I'm looking to have a sound file drive the location of a bone or morph target, to create a basic form of lip syncing. Specifically, I'm looking for help getting the volume of the sound file as a float.
An example of what I mean can be seen in Half Life 1. The scientist has an audio file, and the volume of the audio causes the mouth to open depending on how loud the volume is.
This seems very simple but I havn't really found anything on doing this in Unreal.
