I suggest that rather than making you build a vanilla to-ground connector first, that you just make yours cost straight-up pipe (like the vanilla to-ground connector). Reason for this is that otherwise you get leftover vanilla ones if you only make a single item. I understand that you'd still have a leftover item but at least it wouldn't be vanilla, which at this point, we aren't using at all anymore (apart from for recipes of other things).

Actually, I can't really do that. It doesn't make sense because you'll always need another end. It just lets you customize the other end. In the event of a one off that connects to an existing set, yeah you might run into that. The balancing would be a bit too odd.

You'd end up with one of three situations:
Paying ten for every branch regardless (which means you'll always pay ten too many)
Paying for half of each branch (making the rest of the pack balanced but costing five extra pipes when connecting to a vanilla pipe to ground).
Paying only for the additional branches in pipes which makes the one to one either 10 (double paying), or free, (free pipes).

The vanillas do that because you'll always need a tunnel exit.

I did make the 2 port+ cost only the pipe to ground +10 pipes per branch after the first branch.

Also in next pack will be an updated version of pipe pinging utility that spots pipes with missing connections using a red selection box.

Will also include tiered pipes. May release with just reskin of t1 pipes (yellow. Basically current version new skins). T2 and t3 to follow with 21 and 31 range.
