Yes, I’ve added new node to both versions.
The easiest way to know when there’s an update is check the “Library” in UE4 Launcher. it will display a warning icon the things that have update available in your library…
From there many use perforce diff tools to know what exactly have changed then they merge only the things that matters to their (modified) version of plugin.
I love when they do this because they require less support from me (having a programmer managing this kind of stuff is less margin for human error when dealing with code updates)
For example, I’m not working on 4.18 but 4.19… Have Marketplace version installed on 4.18 and source moved to Project/Plugins on 4.19.
After updating (original code) on 4.18, diff source against 4.19 and merge new lines of new functions needed. Very safe to perform a plugin update this way.
