Sometime we don't want to our agent simulate the finger dynamics or some subtle parts that because it will waste much time also cause problems. There is an attribute on original agents can skip these parts. This can speed up for the dynamic simulation and reduce the problem occurring.
We can now only disable the marked bone and its sub tree, we cannot skip simulate in the middle of dynamics, because it's impossible for physics engine.
Upgrade it if not existed (disableDynSubTree)
Make on the flags on these parts
Under simulation
The agent cache is working no any problem
