Added a struct core redirector in \Config\DefaultEngine.ini, tested in the following formats (not all at once): ```auto [CoreRedirects] +StructRedirects=(OldName="/Game/_Core/Data/Structs/World/Weather/Seasonal/S_OLD_Weather_Season.S_OLD_Weather_Season",NewName="/Script/GameCore.S_WeatherSeason") +StructRedirects=(OldName="/Game/_Core/Data/Structs/World/Weather/Seasonal/S_OLD_Weather_Season",NewName="/Script/GameCore.S_WeatherSeason") +StructRedirects=(OldName="/Game/_Core/Data/Structs/World/Weather/Seasonal/S_OLD_Weather_Season",NewName="S_WeatherSeason") +StructRedirects=(OldName="S_OLD_Weather_Season",NewName="/Script/GameCore.S_WeatherSeason") +StructRedirects=(OldName="S_OLD_Weather_Season",NewName="S_WeatherSeason") +StructRedirects=(OldName="S_OLD_Weather_Season.S_OLD_Weather_Season",NewName="S_Weather_Season") +StructRedirects=(OldName="S_OLD_Weather_Planetary",NewName="/Script/GameCore.S_WeatherPlanetary",OverrideClassName="/Script/CoreUObject.Struct") ``` Redirector is supposed to redirect a blueprint struct asset to a c++ USTRUCT (BlueprintType), however it does not redirect anything. The rules in this example were added one by one during testing. Adding multiple lines at once results in a logged message that there are “conflicting rules”. **Expectation** : Properties, datatables, BP nodes using old struct datatype (BP) should be redirected to c++ datatype. **Actual result** : Nothing happens. ---

Some are the exact same OldName 🙂 But other then that I think that for redirect Blueprint stuff you should do something like this (I have never tried BP to code only code to code): > Blockquote > +StructRedirects=(OldName=“{BlueprintStruct}”,NewName=“/Script/{Module}.{NativeStruct}”,OverrideClassName=“/Script/CoreUObject.Struct”) > Blockquote > OverrideClassName > “(Optional) Specifies a change to the underlying class of the UCLASS.

At one point I tried them all at once just to see if the log would show anything and that’s when the “conflict” message appeared, so at least I know it is doing something. Using the rules one by one results in absolute nothing, not even a log message. > [@ElgSoft](#): > > OverrideClassName I’m going to test this, I thought documentation wrote this for UCLASS only.

Did some test and I can’t get it to work either for BPStruct to CodeStruct. Nothing even happen if I try to redirect BPStruct to BPStruct… Redirect CodeStruct to CodeStruct work fine. So not sure if there are some more magic you need to do or if it’s just broken. ---

Related for c++ to c++ and probably BP to c++, to make the matter more complex the redirector may fail silently after adding it properly. > [Widgets destroyed after moving c++ class from project to plugin](https://forums.unrealengine.com/t/widgets-destroyed-after-moving-c-class-from-project-to-plugin/618739) ---

Hi! Have you been successful? I’ve been trying all day to replace the BP structure with C++. I was able to do it with ENUM, but the structure is unresponsive. ---

Not at all. I gave up fighting. This is another dead / half working feature. Best to start from scratch in c++ and develop modules one by one, then at the absolute last moment implement blueprints if you absolutely have to. ---

Bump, seems to still be broken. I have a blueprint to C++ enum redirector working. No luck with structs. If I had cmd line argument `-DebugCoreRedirects` I get a message confirming when something is redirected… Absolutely nothing when it comes to the structs I’ve redirected, no error, no message, just nothing. ---

I recently faced a similar issue and found a solution, so just wanna share it here. Due to a subtle bug in UE StructRedirects is not processed properly, so if using a StructRedirects I needed to complement it with ObjectRedirects like this +StructRedirects=(OldName=“”, NewName=“”, OverrideClassName=“/Script/CoreUObject.ScriptStruct”) +ObjectRedirects=(OldName=“”, NewName=“”, OverrideClassName=“/Script/CoreUObject.ScriptStruct”)
