The latter is used by BP functions, as well as C++ functions that have default arguments that UHT can't parse (eg, a default TMap argument).

The BP compiler erroneously reports that python nodes might be missing implicit casts. However, UK2Node_ExecutePythonScript nodes handle argument slightly differently than conventional function nodes. The pins don't actually correspond to actual arguments on ExecutePythonScript. Instead, they more or less serve as references to their linked inputs, which ExecutePythonScript will pop from the stack and perform a direct conversion to a Python type. As a result, there's nothing to cast, and we can safely remove the entries from the ImplicitCastMap on the current content.

Setters and getters are native functions called by FProperties when setting property values with *_InContainer functions.
Setters and getter function names can be manually specified with Setter = Func and Getter = Func keywords inside of UPROEPRTY macro but they will also be automatically parsed if the name is not explicitly specified if the setter or getter function name matches SetPropertyName and GetPropertyName pattern.
The latter behavior can be disabled in UHT's DefaultEngine.ini by setting AutomaticSettersAndGetters=False.
ImportText and ExportTextItem functions have been deprecated and should be replaced with *_InContainer or *_Direct variants.

- Removed the meta=(MakeStructureDefaultValue= "1,1,1") from the FTransform struct because Unreal Header Tool is already capable to deduce that from the MakeTransform() default C++ prameter.
- Removed the meta=(Scale = "1,1,1") from MakeTransform UFUNCTION because that can be deduced by Unread Header Toold from the default C++ parameter.
Fixed Python code not invoking the a 'Make' function (declared with meta HasNativeMake on a USTRUCT) if no parameters were supplied to Python (ex. unreal.Transform() would not call the MakeTransform(...)).
- In most case, not calling the Make function worked as expected, but the Make function could implement side effects, so always honor it.
Resaved BP macro assets using MakeTransform() with the default values. The default values saved as string with the asset changed from "1,1,1" to "1.000000,1.000000,1.000000" and this triggered a BP Compiler warning.
The following tests were performed:
- In the Blueprint Editor, added a Make Transform node and ensured the default values for scale were (1, 1, 1)
- In the Blueprint Editor, created a User Defined Struct, added as a member a Transform, ensured the default values for the transform scale were (1, 1, 1)
- Added a Python regression unit tests to ensure unreal.Transform() takes the default scale value as (1, 1, 1) if the scale parameter is not provided.
- Created a Blueprint Macro Libraries with a Macro calling MakeTransform() with default parameters, saved it, applied the fix, got the warning, refreshed the node, resaved the macro and ensured the macro used the correct default scale.
