I have been trying to reproduce this and the only explanation that I have for this is that your base layer (the one on top, with 2D UI) has the property Background set (even set to Transparent). And this is blocking the event propagation to the layer below.

Could you please check this?

Hi Jesus. If this was the case (background is set), wouldn't mouse over events not work? But in this case, they do, but click does not.

For clicks we are using Unity events (move and over events use a different route), we are only consuming the event (when a event is consumed it is not send to next layer that is behind) when HitTesting returns a valid Visual. If you haven't set the Background property, the HitTest should be null in empty areas of your UI.

Could you confirm this?

Thanks!

Sure!

I reenabled this code in NoesisView.cs:

if (HitTest(mouse.x, mouse.y))
{
ev.Use(); // was previously commented out
}

I can confirm 1) mouse enter, 2) over, and 3) click work in the WorldSpaceUI while a NoesisView shows content layered above. I believe the issue I had before was that click events were not working but mouse over was working. It is consistent now, and perhaps I had a background set before?

Here is a video of the current behavior, which I suspect is correct.

If you are in agreement, please feel free to close this out.

Yes, I would say you had a background set (even to "Transparent") before.

Thanks for the feedback!
