Trigger a sound effect (or puppet voice recording)
I wanted to stream two characters at once - one being controlled by mouse, webcam, voice, lipsync etc, the second being controlled by a MIDI keyboard with pre-recorded replays etc. (All he does is grunt occassionaly.) But while I can play back the mouth positions, it looks like I cannot associate the sound track and play that back as well.
Best I can think of is to export a series of transparent movie clips with sound and use OBS, but that is not ideal either as there is no way to “stop the current video and play this other video instead, then record to the first video (or static image) when done”.
Best solution I can come up with is to not stream - just record and upload a video. But then you cannot have an interactive session with the audience.
