To summarize, what should be in Body->state? The set to choose from is:
* position, velocity, acceleration, mass;
* orientation, angular velocity, angular acceleration, inertia.
inertia and mass : no.
The rest should be in "state" since it changes with time.
Oh wait!
Reading this in the blueprint description rings a bell for me :
"Refactor PhysicalParameters into constant part (Material) and variable
part (BodyState)"
1/ Mass is usually constant but it is not a material parameter.
2/ What will happen if one needs to modify the mass of some body during
a simulation?
There is in fact no strict equivalence between "constant" and
"material", or between "body" and "variable".
