It's possible to get bridges that work correctly over lava using a subtraction CSG, but without an option to flood CSGs with lava it looks funky. As for water it's just a pathing issue, you can spam special move commands to make the go under but once you stop they run back through (and around if possible).
Third question: Is it possible to build under it, if so build a teleporter there and send units through it. See what happens. Fourth question: can you build teleporters on the sea? Edit: nope and nope
It's possible to build under the bridges on metal planets though. I think you can even place an inverted radar attached to the bottom of the bridge so it hangs down as long as your camera cooperates. Those can be hard to kill off.
there is no water hieght that allows naval units and land units in same water, tried doing shallow land bridges with no luck
Oh my god. I suddenly see the horrors and nightmares the person designing the placement algorithm must have been through. I mean, who wants to think about area commands on the ceiling?
Isn't this a specific limitation for bridges over water? Bridges over land work fine with units able to operate over and under.....
nope, no madder the distance from the bottom of the bridge to the water ships can not traverse under it
I have played a cool map. Please see figures. Top view Side view Look at the bridge. It can cross other two lower bridges without any pillar. Thus, I think it is possible to build a bridge to cross the river.
I learned the hard way with my map that ships can't go under CSG even when land units can. this was a while ago so idk if anything has changed but I would assume not. it would be awesome if this was fixed. [unrelated note] this is a older picture of the map. there are actually evenly spaced metal spots arround the ring
