>>42395554no, they have cartoony artstyles, but they use live2d. Toontubers is just a term coined for this method that this guy uses where he created a bunch of set animations tied to an OBS filter that you can adjust to make it so OBS triggers each animation when certain criteria are met(like having a regular talking animation and a different talking animation that it switches to when you peak the audio, or having different hotkeys change expressions). The major differences here are that you don't need a separate program to use this as its ran through OBS, and you don't need a webcam or anything like that to use this. Some PNGtubers have used OBS filters like this for basic mouth open and mouth closed stuff, but this is basically a way to make this more animated and expressive.
