.net DLL Blueprint Node

What is inside the DLL’s? If it is some kind of GameObject logic, it could be a problem to integrate to UE4

we have a project that started in unity and got too big for the engine. We are now wondering if its possible to recyle the .net Dlls we wrote as theres a lot of work there. It would be ideal if we could li them in an create blueprint nodes for the functions within, Firstly is this possible? Secondly if so could you please link some documentation to put us on the right path.

Thanks In Advance

Nothing unity specific. Mostly maths and internet coms, all mono complient, No unity stuff, That was all handled in coded classes.

I think there’s gonna be no way if you want to stay platform-specific. You can use a COM interface or something like that, but you will be restricted to windows-

I dont think you can plug in to engine with .NET/Mono dll, why dont you try using C++, math part should be easy to recreate, as for network communication UE4 already have some APIs for that, maybe it has everything you looking for
