Mouse over events not being triggered

I’ve read several questions and answers about the topic and I still can’t make mouse over events work on my project. I can, however, make them work on a plain new project.
Here’s what I’ve done so far:

  • I’ve enabled mouse over events (I’m printing the value every tick and it’s returning true)
  • I’ve enabled Show Mouse Cursor (I’m printing the value every tick and it’s returning true)
  • I made sure all my HUDs have their visibility set to “Set Hit Test Invisible”
  • I ran my game with all the HUDs disabled
  • I set my object’s visibility channel to “block”

Doing those steps should work as they work if I do them in a new project. What am I missing?

I have been struggling with the same problem, but I have made a little progress. First I found I had to add a PlayerStart to the level. And then I found that that my mouse over events actually work fine in a New Editor Window or Standalone game - they just don’t when I run the game in the Selected Viewport or Simulate.

Any hints about how I’ve messed my viewports up?
