I've followed the tutorial video exactly but my model still won't show up in OBS. It just shows an empty square where my model should be. I've tried resetting everything and adjusted every setting but nothing shows. I've used game capture, window capture, and spout2 but the most I can get is the model in a black square with no transparency. Is it an issue with Puppetstring?...
