Like an unique network per planet, orbit, asteroid field, etc?
If this is so, the number is always unique per surface so you can use a decider combinator to "translate" the zone ID to a network ID by using "each" > 0 and output count to your network ID. However, if you use the same network type like "Signal A" for all networks, yeah, you may have conflicts for the mask. I don't have an immediate answer for this problem though
Yea I'm playing with setting a combinator with letters (for the local network) with the value set to match the surface ID. That gets me a surface specific letter. Another guy likes to do a single letter for all but have different netmasks per surface... that might be more complicated. The netmasks have to be bitwise unique.
Ah right, I use cybersyn too, but don't use them extensively in my SE+K2 save. Anyways, I had set the space ship research since I didn't see any use case before that. But yours is interesting so I changed the requirement, now it's unlocked by the circuit network research. I also changed the recipe a bit too, since the previous used processing units, now they use basic green circuits.
