Hi everyone, I created a world with actors and animated box and it is working in gazebo 9 but if i run gazebo 7 this message appears: Error [Element.hh:336] Unable to find value for key[self_collide] and i don't see nothing in gazebo.
Error [Element.hh:336] Unable to find value for key[self_collide] what can I do in order to solve this problem? thanks
