Hello, I am French so sorry if my terms are clumsy.

I am looking to flip a car over to break it and drag it to the ground, and I have the following error on the rigidbodysolver in my dopnet


Warning
rbdpackedobjectMETAL - /obj/Maintenant_dopnet_la_voiture/rigidbodysolver1/bulletrbdsolver: Object (id 0) has zero volume and will be treated as a static object.



I don't know how to solve this problem, I divided the car into several parts (the wheels, the rims, the windows and the body), to which I applied the same modifications and only the body has this problem

It's a little misleading, but delete the pieces that have a zero volume before you sim. You can use a measure sop in a for each sop, to get the volume of each piece. Note that some pieces may be treated as static, even if their volume is greater than 0. If you want to know exactly which ones, after your sim group points with length(v) == 0 (The static pieces) then you can see what their class/name is and delete them before the sim that way
