in reference to [UE-6411] and Can't interact with 3d UMG widgets - Feedback for Unreal Engine team - Unreal Engine Forums i’d like to report that 3D Widgets are still broken in 4.11 and cannot be interacted with.
You are correct is that this is a known issue. I have provide a link to the original issue. Please feel free to visit the provided link for future updates on this issue. I went ahead and double check on this issue as well. This issue’s status has not been updated to fixed as of yet. If you are referring to the comment by Nick Darnell, I believe he was referring to the user’s comment about line traces working with 3D widgets. The issue UE-6411 is different issue. I hope that this information helps.
Make it a great day
