Hello, this is my first time posting a thread, so hopefully I don't mess it up. I just got rendezvousing and docking down a couple weeks ago, and have spent my time making stations around Kerbin, the Mun and Minmus. Now that I've made some simple stations, I wanted to make a "floating city" type of a thing. Please excuse the *ahem* shape of it currently, I plan to have rings of modules radiating outward from all sides, but that's where this problem arises. I've done searching around the forum and wiki about multiport docking, and actually, the two modules connected to the center tower are connected by 2 ports each that both are docked. However, I wanted to test putting a module between them as a sort of corner, but that requires 4 ports to come together. When I tried it, only the top two ports, near the cupola capsule, docked while the bottom two don't seem to do anything. I undocked and came back in with the two lower port angled down so they's contact first, and they still didn't seem to recognize the others and when the top ports came down, they docked again. This caused me to rotate the module as seen in the screenshot above, so the capsule was facing the opposite direction, but the same thing appeared to happen, ruling out the ports on the station. Having just the two ports docked makes the other two appear docked because of the alignment, but they still don't grab. Anyway, I was wondering if anyone has more insight on how docking ports work, maybe code-wise, that could maybe explain this. I know I could install quantum struts to stabilize it, but it would be way cooler to have everything dock properly. I'll try again when I have time, but it doesn't seem to be alignment as much as the ports not recognizing each other. I think it would be a nice feature to be able to right click 2 ports like fuel tanks and tell them to dock if they're close enough, but I don't know how hard it would be to make something like that possible. Any insight would be appreciated, thanks.
