Hey, so I’m making a pretty neat health bar but you can see the corners of the green part sticking out of the health bar, any ideas on how I could fix this?

You could try inserting a UICorner in the green bar.
Thanks it’s much closer now!

any idea how I could have it fill in that small little gap? When I rescale it with roblox it moves it too much and Idk how to use position very well.
Put the order of the green bar behind the white outline, it should look a lot better like that and you can put the bar over the last gap that there is
I think removing the UICorner and after putting the green bar behind the outer one setting “ClipDescendants” in the outer bar (if its the parent of the green bar) to true would make it look more fitting.
For changing the order of showing UI elements see this: ZIndex
