I’m creating an isometric game. When creating the UI menus for it, I created a canvas element set to Screen Space - Overlay. Works well so far when playing the game, but on the scene view it shows incredibly huge like 100x the size of my game elements. The setiting of width and height is also locked so there’s no way to reduce it. Why does this happen? Is there any ways to fix it?
It’s not a problem at all, it’s just the coordinate space that the UI canvas is working in. Your scene cameras don’t render the UI that you’re seeing in the scene view. A UI using screen space overlay is rendered to the screen after everything else is rendered. Depending on the settings and components used, the UI canvas can resize itself to whatever the game window screen size is, or use fixed size values. Take a look at the Canvas Scaler component and learn how to nest rect transforms, anchor elements, and use layout components to build what you need.
