Hi there! I set everything up in VTube Studio with the parameters, but the mouth won't open when I do the TTS test. It opens if I use camera tracking, but doesn't move when using VoiceFrequency2/VoiceVolume2. I tried switching them between the two mouth parameters, but one makes the mouth stay shut, and the other makes it to where it only stays open. Do you have any suggestions on how I can fix this?
