At a glance
Install in the game only; not needed on the server
In order to quicken the building of repetitive features, this mod will allow you to record block placement patterns, then build them instantly later.
Builds require a name, and can be cycled through with a selectable key; cycling while sneaking cycles backwards.
ALSO BE CAREFUL ABOUT USING THIS ON SERVERS!
It should work, but if they have ANY anticheat, it might get you banned!
Build Tutorial
Saving a build requires both Mod Menu and Cloth Config, unfortunately.
Hold your ReBuilder modifier key (alt by default; does not work with the toggle key) and press your cycler key (Z by default). This will start recording without opening the menu screen.
Any blocks placed between starting to record and ending the recording will be recorded.
Open ReBuilder's config menu OR Press the same button combination as what you used to start recording.
If you exit without saving, build progress will resume with no changes.
