I need a liquid and glass wall for a building. It needs to direct steam up, and when it's lower than the boiling point, it falls into a tank (for reuse). What I'm trying to do is complicated, so I won't explain it. Is there a wall like that? (And if there's not, just tell me, I'm an expeirenced developer, and I've made custom elements for TPT before, I just don't want to waste an hour or two for something that may already exist)
Edit: And if its a user-made mod, that's fine too.
And this is why even the mods find you anoying. He provided plenty of detail for a wall, even a usecase.
I'm assuming you mean "liquid and gas", not "liquid and glass", so I'll just answer that :P
Depending on what exactly you're trying to make, it might be possible to use both walls side by side, or in a pattern of some sort. If that wouldn't work, you could try store+pipe, with specific ctypes to let steam and water through (though that really limits the flow rate).
Aside from that, your best bed is a mod
