I’m currently working on an inventory system. I just made simple buttons and texts.
I open my inventory with “Tab”. But when I click on a button and press tab, it just highlight buttons (like on window).
I have to click somewhere else to be able to close the inventory with “Tab” again.
I read that changing “Render focus rule” to Never in the project settings might be the solution, but it doesn’t work.
I had a similiar problem.
Fixed it by adding the node “Set Focus to Game Viewport” when pressing the tab key.
This will put the focus back on your viewport.
