So here is my problems
1. I'll do all the physics how all the tutorials say and it will look perfect but when I export they don't work with vtube studio, prprlive, etc etc
2. when I do physics then leave and come back to physics it resets the output max % to 0 and won't let me change it.
I just don't get I literally follow every tutorial step by step and this happens every time

Thank you for your contact.
This is Live2D Support.
Check if it works with Cubism Viewer.
If it is working properly, check the specifications of the third party product.
The maximum output value (%) will not change unless you manipulate the model in the view area of the physics calculation setting screen.
This value is used to check the movement of the model, so it is always set to 0 when you reopen it.
For details on how to set up a model using the maximum output value, please refer to the following link.
How to set physical operation:https://docs.live2d.com/cubism-editor-manual/physical-operation-setting/?locale=en_us
However, we have found a bug in version 4.1 beta1 and later.
Please check the following post for details

hope that helps.
