Unreal Engine, as well as .NET runtime, utilizes a garbage collector for memory management. The framework is designed with consistency in mind to prevent crashes and validate memory transparently for a programmer, no matter how objects were created and freed: with C++, C#, or blueprints.Я так понимаю, не особо сильно усложнит жизнь. В UE тоже свой GC для C++ объектов используется, насколько я знаю.
