Blueprint component lost when reparenting native base class and component name collides

Use attached project to skip c++ steps. Follow from step 6. Update: It appears that the same symptoms occur if you simply change the name of an existing subobject, without changing the property/f ...

Nativizing a blueprint interface using TMap/TSet causes Fatal error in UHT

FPropertyBase constructor does not handle a TMap/TSet property. Following workaround can avoid this error. explicit FPropertyBase(FProperty* Property) : PropertyExportFlags(PROPEXPORT_Public) ...

Functions containing Unicode characters break nativization on Clang-hosted target platforms.

The UHT boilerplate code that's generated from a converted Blueprint class header file generated from a Blueprint class containing one or more function names with non-ASCII characters will fail to c ...

Redirecting a BP enum to a native type enum causes the old name to be "none"

BP editor - Unable to edit details of a native component named as 'RootComponent' in C++ code.

Looks like maybe the PropertyView stuff doesn't like it when the subobject name matches the parent's object property name? In this case the CDO is the object that will be selected to the PropertyVie ...

Make/Break Struct node breaks for native structs after modifying the structure in a hot reload

Changing and compiling a custom struct in C++ will break behavior of Make/Break Struct nodes in blueprints if the blueprint is saved after the compile. Regression: No - blueprint fails to save afte ...

Hotreload on c++ native actor component class will cause BP edit malfunctioned

[Image Removed] When the BP editor is opened, hot-reload compile will wrongly serialize a HORRELOAD_XXX object into the BP class and package which can not be found when Editor is opened again after ...

Bluerpint nativization failed for calling TMap::Find function of a map container with an enum type key

Followings are nodes in the repro project. [Image Removed] Here's a generated code of the BPvoid ANewBlueprint_C__pf1010915279::bpf__NewFunction_0__pf() { uint8 bpfv__CallFunc_GetInt_NewParam ...

UClass::SparseClassDataStruct null at editor-time for child blueprints until compile

Child blueprints of a blueprint of a native actor class with sparse data can have an incorrectly null SparseClassDataStruct value, and thus fail to initialzie their SparseClassData. This affects edi ...

BP - Editing defaults on a nested subobject of a component inherited from a native parent class won't preserve those defaults when the BP is instanced.

I think the issue is that in GetInstancedSubobject() (CoreNative.cpp), the following bit of code is not considering that the instanced subobject might be outered to another instanced subobject withi ...
