About the difference between mesh operators and spline paths

[masa]

This is an English forum…

Sorry, it was translated automatically.
Mesh operator doesn't affect simulation on/off, but re-simulation with spline path on/off is unavoidable?

Another thing, in order to separately export the spline paths of different events in the same flow, I thought that it would be better to put an export operator in each event and write it out, but as a result the spline path in the flow is all written out. this
Is there a better way to go?
thank you.
