Fluid Extras - Junctions and the "junction height bug"
This post is mainly meant to be informative.
In vanilla, junctions exhibit a certain height bug when they are vertically aligned and in a certain rotation.
This bug can allow fluids to be split even when some of the pipes arent fully filled, as well as allowing the pipe headlift to be "extended" as can be seen in the images. (A mk 1 pump was used yet the pipes manage to fill and flow far beyond 20 m)
Ive now tested (almost) all junctions from Fluid Extras and found the following:
- Any Junction that has at least 3 connections and at least one of those connections is not on the same "height" as the other ones can exhibit this bug.
- Notable exception: the Tri Junction is not symmetrical along a single axis. It only has rotational symmetry. Due to this, there is no orienation where is can reasonably be used to exlpoit this bug. It likely still exhibits it, but only in positions where chaining of junctions (for manifolds for example) is not possible.
- Junctions that are not symmetrical along one axis yet have their main connections ( connector 0 and connector 1 ) in one line can exibit this bug as long as other connectors are vertically offset from them, such as the Junction Fork and the Pipeline Balancer.
Tested junctions that exhibit this "bug":
1) T Junction
2) Double T Junction
3) Junction Fork
4) Pipeline Balancer
5) junction L
6) Junction Cap Cross
(Still testing some other junctions)
