Why won’t my Live2D physics move? Maximum Output is stuck at 0

kimuhayekimuhaye
in Help

I apologize for being awkward using a translator, please understand.

Hi! I’m having trouble with the physics settings in Live2D Cubism 5.3.

I created keyforms for the Hair Front parameter to make the hair move.

Then, in the Physics Settings, I set:

- Inputs: Angle X, Angle Z, Body rotation X, Body rotation Z

- Output: Hair Front

However, when I move the mouse to move the character, the pendulum doesn’t move at all, and the hair doesn’t move either.

Also, the Maximum Output value for the Hair Front output is set to 0, and I can’t change it.

I’m not sure what I’m doing wrong. Is there something I need to set up or enable for the physics simulation to work?

I’ve attached screenshots of my Physics Settings and the Hair Front parameter.

Any help would be greatly appreciated!
