Hi everybody!
I got a problem here. I have a GameObject with box collider and ConfigurableJoint. When I drop something on it (primitives), it doesn’t collide! The primitive object just pass through the object that holds ConfigurableJoint. I tried several things to track the problem and nothing. Then I just changed ConfigurableJoint for a HingeJoint, tried the same “drop object on it” test and collision was executing perfectly.
Unity Team, please, fix it!
You need to submit a bug report. It is also not a bad idea to attach a package here first, such that others may try to reproduce your issue.
