Actual Behavior

error : Native pointer usage in member declaration detected [[[URoom*]]]. This is disallowed for the target/module, consider TObjectPtr as an alternative.

Additional Context

As on Unreal Engine 5, TObjectPtr is the new way for classes to hold raw pointers.

Hi @oivio

I know TObjectPtr is the way to go in UE5, however since I'm also targeting the code for UE4.27, I can't use them yet.

I have no issue to build the plugin for UE5.7 because I don't enforce that on my projects.

So depending on your requirements, I would suggest you to:

• set NativePointerMemberBehaviorOverride = PointerMemberBehavior.AllowSilently in your project's Target.cs
• or if you must enforce that, use the tool provided in the engine to convert raw pointers into TObjectPtr

When I will drop support for UE4.27, I will convert all the raw pointers into TObjectPtr though.
