We're expanding our Q3 Physics Engine by joints.
We will support Fixed, BallAndSocket, Hinge/LimitedHinge, Spring, Prismatic, Buoyancy, Magnet joints.
Of course configurable at design time.
They also will be breakable by force/torque and you can configure motorization (as in the buoyancy example).
We've made layers-mask accessable at design time. Group rigid bodies up into 8 different layers for collision detection.
