There are many instances where you need to connect things to each other, like Grasshopper to an external Python application, or Rhino to Unreal Engine, etc. You might have come across interprocess communication – IPC – methods as a solution to this issue. To address this, I have written this code. The description on the GitHub link should be sufficient to get you started.
I have tested it on Rhino 7, 8, and Unreal Engine 4.x and 5.x, and it worked.
