I think this is the correct docs for that.

Hello everybody. I noticed in some community codes people using a meta specifier called AllowPrivateAccess this way:

UPROPERTY(BlueprintReadWrite, meta=(AllowPrivateAccess = "true"))
float YourPropertyName;

I searched in THIS LINK but I can’t find anything related in official documentation.

Thank you,

With AllowPrivateAccess, one can create classes with private C++ data (hidden from non friend classes) while allowing Blueprint derived classes to access it. I tend to use this to encapsulate data in C++ but make available in a read only manner in blueprint, reducing the number of getter and setter functions.
