Hi, I’ve encountered a 3d widget interaction problem in UE 4.9. As in following picture, widget accepts mouse events in incorrect positions. ![57110-3dui1.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/9/f/c/9fcb168c3ff93a57d9569bad82a3581a8e8c70ab.png) I created this new blank project for testing. (I encountered this problem in my current project also.) When the first time I created this new project and the widget in the scene, it works properly. Widget can detects mouse events normal. But after I closed the testing project and opened it again, it’s all gone wrong, UI mouse detection became weird and I don’t know why. Here’s the link of my testing project: [Dropbox - UITest.zip - Simplify your life](https://www.dropbox.com/s/f8f8ur03x5a6sfb/UITest.zip?dl=0) Open the project and it should loads test scene directly, press play and move mouse around and you should see the problem. I’m not sure if it’s a bug or something I didn’t set correctly. Can you help me with this issue? Thank you. ---

P.S. Change widget pivot to 0,0 in component setting won’t work, it would cause UI rendering occlusion issue. ---

Hello CrispyVitamin, I was able to reproduce this issue on our end. I have written up a report ( UE-20777) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information. Make it a great day ---

It seems the hit boxes compared the the actual widgets being shown are rotated 90 degrees. So if I have three buttons stacked on top of eachother I have to move from the lower right to the lower left to highlight them. ---

Still doesnt work in 4.10 and now the pivot workaround is gone too. I would give anything to have started my VR project in Unity. ---

I had the same issue on 4.10 in standalone game. I made new blueprint with widget and it worked fine. I had pivot in 0.5 0.5 and rescaled it and it worked too. ---

having the same problem in 4.9 right now. Changing the coordinate space from “world” to “screen” on the actor’s widget component works nice. So i think it might be a problem with the screenToWorld/worldToScreen projection of either the input or the event area of the widgets.
