My first model with bones =]
You can open and close the gate moving the empty object to up and down on the Z axis.
This is a model of a automatic gate that you can find and some of the houses on Brazil, the mechanism is called as basculante, something like you can find on a dump truck.
I find some problems to limit location on the empyt object, some one could help me? I want to move de object but lock de moviment only on the Z axis, I tryed to set parent, but don't work.
I hope you enjoy.
