Hey Allison,
1 - Use the EventAfterTime.cs compontent to pick when you want to fade to black
2 - Have it update the Screen Fader . SetFadeBool(bool fade)
3 - Have it (or another EventAfterTime.cs) play the audio file from. Tip: You dont need to animate the face with lipsync if you cant see the face, just play an audio file direclty from the audio source. You can still make the sound come from the characters mouth by finding the audio source parented under the bone structure of the character
*This method wont be so helpful if you are using branching, as you cant predict when a user will finish as easily. I will try and build a solution into fix this
