So, I have ported this plugin to Unreal 5. Works fine, the C++ engine adapted well to UE5.
However, the C# architecture that I have built for this plugin, there’s some serious blocking changes in the core of Unreal 5 that makes it impossible for me to compile C# DLLs within the Unreal Editor now…
I suspect I will be forced to drop the C# project and wait for Verse scripting, I have done all I could with the C# VM, but it just won’t load any CS DLLs anymore on Unreal 5, and blocks the Editor from launching which is a no no no.
So for now, I move on and keep support for the C++ node only.
