For example:
AND gate
OR gate
NOT gate
NAND gate
NOR gate
EOR gate
ENOR gate
Scenario 1
If you want to turn on all lights in a room, for example, you have a button widget that allows you to manipulate simple logic E.G. IF , SET linked lights to ON
Scenario 2
I made another feature request that is Interactive Toggle, you could build this and that feature to work together so for example, you can link a door/blinds to a smart home screen that allows you to open or close it. The smart home screen in question can be a widget, and you can change the mesh for it. Think of a Google Nest Hub.
If there was such a feature, I would not need to use Unreal Engine for 99% of my Archviz projects.
