I often face problems when I try to do blueprint nativization. The biggest one occurs when there is a cooking. And when cooking fails I don’t understand what blueprint causes the problem, so it takes time to find the problem and optimize the blueprint. That’s why it would be easy to do nativization before cooking.
I know that it’s hard to develop such functionality, but still, it would be useful to developers.
Indeed, maybe something like that would help: BP Nativization in editor / 'Compile to C++' button - Feedback for Unreal Engine team - Unreal Engine Forums
