>>78787basically this
being a vtuber is just being a streamer but using an avatar in place of a facecam
now if the question is like, how do i get an avatar for vtubing without having to pay someone that's a whole different question but you basically have to draw your character, separate the .psd in some specific way that a tutorial could teach you, and rig everything in Live2D
then you just import that model into a program like FaceRig or prprlive
