How to move terrain widget to bottom left

Hello,
In the 3rd Argon Assault video, Rick’s terrain has its origin point set to the bottom left by default, but mine is set to the centre. He does point out this may be the case, but doesn’t actually tell us how to fix it. Any help would be greatly appreciated.

Hi Camico,

Please check the two buttons next to the play button. Are they set to “Pivot | Global”?
