Hello sergio,
The requested functionality was to allow for public variables created in the blueprint to be able to be edited when the blueprint is being used as a child actor. This seems to be working in 4.14 from my testing. Can you give me a scenario where it isn’t? Here’s a picture of what I’m seeing:
This is inside of the Details Panel for the Child Actor component in my ContainerBP. My other BP (MyBP) contains an Int variable called MyInt. After adding the Child Actor Component, setting the Child Actor Class to MyBP, I was able to edit this Child Actor’s variable (MyInt) through the details panel.
If there is some other functionality that you were looking for, please let me know and I can add a separate feature request.
