Offset means the amount of pixels the UI is currently taking up So if I have a 1920x1080 monitor, and I have a UI that’s 500 pixels both X and Y, the size is fixated at 500 pixels.
But if I have a 1280x720 monitor, that UI is gonna look bigger because it isn’t scaled to fit that monitor because of the pixel count.
How would that benefit you if you set the anchor point to 1? The UI is still not gonna be scaled properly so I’d suggest using a UI scale if that’s what you’re trying to accomplish
