Very nice. It works as a gate, just open and close. It fits vertical gates best.
EDIT:
Actually it doesn't fit any of the gates I'm afraid. The model is rotated 90 degrees off from the gate models. This means when you use it as the Art -Model for a gate, the pathing and the model will not line up. E.g., if you put this model in as "Iron Gate (Horizontal), the pathing will be horizontal, but the model will appear vertically. You can change the "art - fixed rotation" but that will rotate the pathing as well, leaving the model and the pathing always off by 90 degrees.
This, unfortunately, appears to make this model useless for use with gates unless you do all the pathing manually with pathing blockers and such.
Incidentally, rotating the model 90 degrees will not solve this as it throws off the animations.
