Hello, I want to ask the teachers about ziva spine binding. In the maxsym or addsym project file, the original spine binding is used to simulate muscle ziva solution. It is found that if the zSolver substeps parameter is set to 2 or more, the name is c_ ribCage_ The volume's tisue is like being nailed to its original position and cannot move with the skeleton. Is this a bug? Is there any other solution? How did you do it!![https://s2.loli.net/2023/01/03/auYy2e6NVQM5CDx.png](https://)
