Summary0003979: Mouse click is not working in Unreal Engine screen space widget components
Description

Hi there,

I'm having an issue with Unreal Engine 5.5.3 (latest) and Noesis 3.2.7 (latest). My problem is that according to the docs, Noesis views (widgets) should work fine with widget components (UWidgetComponent), however, if I try to place a Noesis view inside a widget component in the world, the contained UI does not receive mouse click events. (hover works fine though) It seems to give back focus to the game viewport.

The widget component mode is set to screen space, so it's always an overlay of the world, not really what Noesis World UI implement.

I've tested the issue with a fresh empty UE project to make sure it's not my project settings are causing the issue.

I parallel tested with regular UMG widgets, and they do work fine in the very same situation.

Hi,

There was a problem when using Noesis with WidgetComponents on screen space. The attached fix resolves it, as well as another error message related to clipping that I noticed while testing this.

Please, let us know if this resolves your issue.

Thanks!

Hey there, sorry for the late response! I've tested your solution, and unfortunately, it does not seem to work on my side, moreover, now hover also seems to be broken. I'm testing with a Button with a ControlTemplate of a round ellipse.

Sorry, this ticket fell through the cracks.

Could you send us your XAML? I've just retested it with the XAML from our Buttons sample and I can interact with it correctly.
