Ok, thanks.
Now, here is my problem : I have something that must be done only once for each object,
either during scene construction after constructor call (using the py function
"chainedState"), OR at reload time.
If the constructor is calling the corresponding code, it will crash. Same if it is done
twice in a simulation.
I understand postLoad will not do the trick.
Is there a way to execute something at load-time only?
