Units seeing through a gate, only when open

[Cienfuegos]

I've had trouble keeping units from seeing and attacking units on the other side of a gate, I was hoping for some way to make only one side of the gate able to atack the other.

In the object editor on the destructible theres a field called "occluder height"

If it's currently zero, change it to something higher and try that out.
