I have two objects that I wanna ally in pairs.
I have a Door and a valve.
Both have an ID value, and the valve has an activation rate.
I want the door to open partly using the activation rate.
However, I cannot see how to do this. How to retrieve the correct activation rate value in the door's width expression depending on the IDs.
Because the thing gets glitchy when I have more than one door and one valve.
