Gracias, por cierto, se podría decir que ya tengo mi modelo(o más bien render PNG), no es la gran cosa, pero... ¿con algo se empieza no? Es este, porfa no me funen:

Volví al foro a revisar y concuerdo con absolutamente todo lo que dices! Excelente respuesta 😄
Sobre lo del alza de videos en formatos cortos guionizados, si me gusta mucho que Rin Penrose lo haya vuelto a popularizar, recuerdo que la primera vez que vi uno de sus tiktoks hablando de como funcionaban las agencias me alegré mucho y desde ahi me cae re bien jeje, tbh el contenido en tiktok de vtubers tiende a ser muy formulaico y siempre sentí que no explotábamos mucho el potencial del vtubing y su anonimidad para hacer cosas más interesantes en tiktok. Intentaré aportar mi granito de arena en ese aspecto, aunque tbh con la llegada de las inteligencias artificiales es cada vez más complicado 😭

Sobre los NPC Streams, creo que varios hemos bromeado al respecto pero nunca he visto a alguien realmente haciendolo!!! Es un potencial money hack y por eso ya veo que alguien lo hace con una vtuber IA en los próximos días o semanas...

Sometimes, cloth has to follow the body only when being squished by it. Rigging it directly to a bone would make it unnaturally follow it when the cloth is not actually being squished!

Tutorial What you need Basic Blender knowledge: Modifying meshes, and managing of blendshapes The VRM addon for Blender Steps In Blender Import your model into Blender, and, for your own sanity, properly separate the piece of cloth you want to be squished from the rest of the clothes.
d898cf09-18dd-4bb5-aa46-96bb68c9398e-image.png Rotate the bone to its humanly possible limit. In this case, any rotation of the neck bone in the X axis greater than 5° caused clipping, but I increased the rotation to something that looks like a reasonable limit for neck rotation. Take note of all the angles you work with, in this case, 5° and 22°.
6cf2dbf8-4b68-45a9-bbba-10ca167a01ba-image.png Select your mesh, and create a new blendshape. Name it something descriptive, in this case, it's Neck Forward. Modify this blendshape such that the cloth no longer clips in the set bone position.

Since it's a common movement, you can create two additional blendshapes for each side that will activate along with the first one, blending and making the cloth follow the chin a bit better. I called these blendshapes Neck Left and Neck Right.

We now have to setup VNyan to check the neck rotation every frame, and if it's beyond the 5° rotation on the X axis, start activating the blendshape, blending it until the 20° limit, when Neck Corrective Down should be at its maximum.

Here's a quick breakdown of the node setup:

This part just sets up a loop for vnyan to run every frame
52f8f060-b872-40c2-9ea4-0854bcd789f4-image.png Next, it gets the value for the X rotation
600d9a7d-484d-47a9-9290-3193bbed164f-image.png And checks that it is between the 5° and 22° range. If it passes, it sets the new blendshape value.
984b0df0-03ab-46b7-b836-9c15967ec30c-image.png The value for the blendshape is determined via a linear interpolation that maps de 5°-22° range to the 0-100 range. If your range goes from a to b, you have to substract b to make it go from 0 to a-b, and then multiply it by 100/(a-b), making the range go from 0 to 100. Here, a=5 and b=22
1cc783e6-4b4c-4b1e-b40a-4c171393c950-image.png (Optional) You can use the ordered execution node to make it also check the Y axis and apply the other two blendshapes as needed. You can just define the angle limits by what angles you used in blender while setting up the blendshapes. Don't take this screenshot too seriously, I didn't properly note the angles I used so I just guessed numbers, but it gives a general idea of the process of checking another angle along with the first one.

And so, every frame the blendshape values are updated smoothly between 0 and 100 depending on the neck rotation, squishing the cloth as needed!
b7b93bf5-ee21-4e9d-bce1-5fc7a6971c1b-image.png Notes You can do this for a bunch of bones, use the three axis of rotation, and mix and match conditions to suit your desires. It may even start to look like a Live2D setup. Be careful though, you roughly duplicate the amount of blendshapes needed by each degree of freedom! Two bones can need up to 64 blendshapes, one for each possible range of positions! This can probably be done in Warudo too!
