>>45018272>or does just a webcam work?Short answer no, long answer yes but...
There are a couple apps that can capture your motion with a single webcam and send it to vseeface but it can't be the same one you use for your face and it's pretty much impossible to set up.
It needs to be able to see you facing it from your head to toes meanwhile you have a desk and computer and mic blocking it. And normal webcams don't have that field of view. (I can try to find a program if you still want to play with it)
If you want to use trackers there are two categories, vive/tundra that use towers you install in your room or slime vr that uses acceleration to calculate movement (slightly less precise).
Slime vr is probably cheaper if you don't want to use a headset but vive or tundra are better investments long term.
What I'd recommend instead is making an idle animation or getting one off

But vseeface will capture it if you sway your body from side to side, also how much can you dance while singing? It's pretty hard yo!
