To be honest, PNGTuber avatars are a waste of screen space. You see them speak once, and you’ve already seen their full range of visual emotions. If you’re going to have an onscreen avatar, it had better be as expressive as you are. I’d rather see the default VRoid Studio model with tracking than two commissioned poses.

Most streamers are better off having fullscreen game video. There is absolutely nothing wrong with fullscreen game video. I did it that way for 11 years.
