How do you make a hinge controlled by an activation group?

@Mnmnmnmnmnmnmnmn you’re welcome :)

@LeMagicBaguette Tysm I'll credit u in the description of the rover

You need to enable advanced properties under additional settings. Doing so will allow you to directly edit the input by tapping on the text displaying what the rotor input is currently bound to. When your keyboard pops up, replace the input (probably Slider 1) with the group of your choice. AG1 for group 1, AG2 for 2, and so on.
On PC, I’d imagine the process is similar. If not, then use the inbuilt Overload found in your tinker panel. From there, execute the aforementioned process.
