Model cant move besides face tracking | VTube Studio Headquarters | Page 1

my model used to work but i was following a youtube tutorial as this is my first time rigging a model. the youtube tutorial went over the physics in vtube studio so i checked that out in the app but my character was moving really fast so i reset the setting and thats when my model “broke”.

it couldnt look left/ right but the mouth could move and it could blink same with eyebrows. if i moved my head really far up/down it would follow along a little bit but if i moved my head to the side the entire model starts floating side to side.

i tried the button that resets all app settings but i dont know what that does since im new. it’s been a month since it broke and i have no clue how to fix it. i couldnt find anything related to it on reddit or the faq/ vtube documentationthing that was listed

(first video is what it is now and second video is one from when it worked)

Can you send a couple screenshots of the parameter settings tab?

is it these settings? or is it in another place

clever junco Apr 22, 2025, 4:17 PM

#

Yes, those settings

Hmmm those look like default values. If you click the gear next to Physics Strength, do you have anything thats different from default?

#

wdym by default

clever junco Apr 22, 2025, 4:43 PM

#

I believe all parameters should be set to 1 within that menu

When you rigged the model what fps did you set in the physics window?

lost adder Apr 22, 2025, 4:47 PM

#

idk

#

i can check when im back home

clever junco When you rigged the model what fps did you set in the physics window?

it says 60fps

#

for calculated fps

clever junco Apr 23, 2025, 12:44 AM

#

Your vts should match that then

ok

this?

Yellow icon lock button

#

Or if you really want to force the body from shifting as much, you can create something for pos y and pos z, and make the output 0 so the model isn't flying all over the place

i already pressed it but my model wont react

#

i noticed that the input and output area the numbers on the left move but the numbers on the right are stuck is there a way to make it move?

does anyone know

clever junco Apr 28, 2025, 5:42 PM

#

Do you have an expression active that is limiting those parameters?

lost adder Apr 29, 2025, 6:54 PM

#

what kind of expression?

#

The only thing that comes to mind here is "restart the app on the phone, while holding it in portrait mode"

#

Because if it's your daily driver, when the app goes to the background it retains the state.

#

if it rotates between the last time the app was loaded, it ... uh, doesn't know that.
