I’m having issues trying to get my Viewport back into my editor. Currently my viewport is in a popout window and when I click the viewport tab and try and drag it back into the editor it does nothing. I can drag the viewport onto the details pane, content pane or any other pane except the center viewport pane.
Go to Windows in the top right corner of the engine click on it. Go down to viewports, click on viewport 1 opens up your editing tab thingi. Drag that to where it used to be and you’re good.
