Just something we discovered after trying out this great item. The connections to it are shown if you hover over other items. but if you hover the mouse over the 4-4, nothing is shown. In fact, you can't distinguish it from a pipe at all, so if you connect two parallel aboveground pipes via this, you'll never find it by looking.

I feel like you didn't read the mod documentation. A lot of questions you have are written there.

It's a pipe. Pipes aren't designed to show their underground ports. This is a game engine limitation.

I also am not gonna create arrows for that. There's so many variants of graphics for a regular pipe that it would just get insane.
I was going to take the cross pipe one and lock the graphic to that and add cross arrows. I can convert it to a pipe to ground at this point which will show the underground lines, but then the pipe is locked into a cross graphic.

no sorry I wasn't referring to how the pipe itself appears. That is fine. I was just saying that you don't get the underground dotted yellow lines when hovering over it with the mouse, which makes it hard to tell what it is connected to. But if that's not something the game can show then that's okay.

I might be able to actually write custom scripts 🤔
Don't want to get super ups intensive though.
