Changing a BP parameter from a split struct to another type is not reflected in editor

Hi RicarDog,

Sorry for the delay.

I was able to reproduce this so I’ve created JIRA UE-47328. Our developers will be investigating further. Follow that link to monitor the status of the report.


  1. Create a blueprint function.
  2. Add an Input of any struct type, e.g. Box.
  3. Right-click on the input and select “Split Struct Pin”.
  4. Change the input type to a Boolean. Notice that the Box pins are still there.
  5. Compile the function. It compiles successfully, even though the input type has changed and it’s not reflected in the editor.

The same happens with output parameters.
