i am generating constraints during a simulation and i would like them to be more rigid by somehow restricting their rotations so that the generated structures keep their shape.
i am using hard constraints with constraint type set to all.

i saw there is a rigid angle constraint node but i don't know how to use it, even if that would be the solution i don't know how to generate it inside the simulation. The constraints are just lines with attributes. Is there an attribute i can set to force the constraints to stop rotating so much?
For example if a Y shape structure is generated how can i force it to keep that shape so that the lower constraint doesn't flip around in between of the other two? its difficult to find example scenes

Hard constraints (with constraint type set to all) should keep the relative rotation between the constraint anchors the same. However, if they aren't being completely enforced, that's a sign you might need more constraint iterations on the solver
