Ah I see, so each of the values that are shown in the inspector should become its own observable object? That sounds reasonable. > But in reality it's probably re-rendering the entire hierarchy using the @EnvironmentObject. So the SceneKit view gets setup and rendered every update of the Slider. I get that this is slower than only updating the single value, but what I don't understand is why even this is so slow? Browsers can render the right hand side of this inspector UI (https://chsxf.dev/assets/posts/5/map-editor-with-inspector.png https://chsxf.dev/assets/posts/5/map-editor-with-inspector.p...) at reasonable speed even if you rebuild the entire DOM for the fields in the inspector. I mean, it's one checkbox, one slider, and 7 text boxes and a bunch of labels. What is taking so much time here?
