I’m currently in the process of searching for a way to interact between UE and another application, essentially pushing bits of data to UE.
While searching, I found “BackChannel”, a built-in plugin, but there are almost no information about it (What it does, How to use, …) and it might be what I’m looking for.
Does anyone have information’s? If it doesn’t allow what I’m looking for, is there another way of doing it?
So BackChannel looks like a communication plugin, which can be used to communicate (currently) over TCP/IP with OSC devices.
Going through the plugin source code, it’s clear that in its current state, we cannot access any of its functionality via Blueprints. If I’m not mistaken, what you want to do is just create a comm link between UE4 and a random third party app, so, I would recommend that you look at the following .h/.cpp files:
Rip the code out from there, and put it in a custom actor/utility class and expose the functions you need to BP.
This is not really what I searched for and the lack of documentation is a bit annoying.
Thanks for the search.
Note: I don’t want to use BP if possible.
