I am very new to Houdini. I'm working on an animation where two rigid bodies are falling to the floor and one of them is hinged to the other. I have seen the hinge constraint and have connected to one of the objects but don't know how to connect to the other rigid body. Also the hinge does not fall with the object. There is probably a better way to do this but like I said I am new.
Thanks

Here's an example hip. All you need to do is have two rbdobjects, and use their names in the constrained object and goal object part of the hinge constraint.
In that same node, constraint location is the position of the hinge, and constraint direction the axis you want to object to rotate around.

Awesome, Thanks!
