A program that can be used to mod Galaxy Union, used for creating the commodity relationships in the game. This tool can also be used for your own projects, it can export an item tree as XML and CSV.
This mod tool was used to create a world tree that contains nearly all entities in Galaxy Union, from Periodic Elements to Station Components. This tool can be used to heavily alter the game. However there are some limitations in the logic that can be used. Galaxy Union will handle most configurations of the World Tree, but some entities are hardcoded, if you wish to MOD the game, please do so in small increments. Changing required item amounts is the easiest and safest way to get started.
