Hello there,
I created a Struct with the visual tool accessed by right-clicking into the content browser, selectecting Blueprints → Structure.
How do I get access to it inside another C++ Class to use it, as say an Input or Output?
As far as I know, there is no easy way to get access to a blueprint struct in C++.
You can use serialization to achieve it but I would recommend to implement the struct in C++ and give blueprint access to use it, this is way easier and the standard way to do it.
